The shortest answer -

Arch has really good documentation and a release style that works for a lot of people.

Ubuntu is coorporitized and less reliable Debian with features that many people dont need or want.

Arch requires reading the manual to install it, so installing it successfully is an accomplishment.

It's rolling release with a large repo which fits perfectly for regularly used systems which require up-to-date drivers. In that sense it's quite unique as e.g. OpenSUSE Tumbleweed has less packages.

It has basically any desktop available without any preference or customisations by default.

They have a great short name and solid logo.

Arch is community-based and is quite pragmatic when it comes to packaging. E.g. they don't remove proprietary codecs like e.g. Fedora.

Ubuntu is made by a company and Canonical wants to shape their OS and user experience as they think is best. This makes them develop things like snap to work for them (as it's their project) instead of using e.g. flatpak (which is only an alternative for a subset of snaps features). This corporate mindset clashes with the terminally online Linux desktop community.

Also, they seem to focus more on their enterprise server experience, as that is where their income stream comes from.

But like always, people with strong opinions are those voicing them loudly. Most Linux users don't care and use what works best for them. For that crowd Ubuntu is a good default without any major downsides.

Edit: A major advantage of Ubuntu are their extended security updates not found on any other distro (others simply do not patch them). Those are locked behind a subscription for companies and a free account for a few devices for personal use.

I don't know about everyone else, but the last couple of years has had the most unstable Ubuntu releases, with the most unrecoverable releases when issues happen.

I've since moved to Fedora for desktop and straight Debian for server.

I don't really have a concise answer, but allow me to ramble from personal experience for a bit:

I'm a sysadmin that was VERY heavily invested in the Microsoft ecosystem. It was all I worked with professionally and really all I had ever used personally as well. I grew up with Windows 3.1 and just kept on from there, although I did mess with Linux from time to time.

Microsoft continues to enshittify Windows in many well-documented ways. From small things like not letting you customize the Start menu and task bar, to things like microstuttering from all the data it's trying to load over the web, to the ads it keeps trying to shove into various corners. A million little splinters that add up over time. Still, I considered myself a power user, someone able to make registry tweaks and PowerShell scripts to suit my needs.

Arch isn't particularly difficult for anyone who is comfortable with OSes and has excellent documentation. After installation it is extremely minimal, coming with a relatively bare set of applications to keep it functioning. Using the documentation to make small decisions for yourself like which photo viewer or paint app to install feels empowering. Having all those splinters from Windows disappear at once and be replaced with a system that feels both personal and trustworthy does, in a weird way, kind of border on an almost religious experience. You can laugh, but these are the tools that a lot of us live our daily lives on, for both work and play. Removing a bloated corporation from that chain of trust does feel liberating.

As to why particularly Arch? I think it's just that level of control. I admit it's not for everyone, but again, if you're at least somewhat technically inclined, I absolutely believe it can be a great first distro, especially for learning. Ubuntu has made some bad decisions recently, but even before that, I always found myself tinkering with every install until it became some sort of Franken-Debian monster. And I like pacman way better than apt, fight me, nerds.

 :: Searching AUR for notes...

 -> Missing AUR Packages: SideNote

 there is nothing to read

Is it really? I've always understood the cult around it as a joke.

But seriously, RTFM.

Arch has a very in-depth wiki that's the go-to resource for a lot of Linux users, and it offers a community-driven way to have access to literally anything that's ever landed on Linux ever through the AUR. It's also nice to have an OS that you never have to reinstall (assuming all things go well).

Why that turned into such a cult-meme is anyone's guess though.

I just think its good.

The way I see it, you can have an OS that breaks less often and is hard to fix, or an OS that breaks a little more often that is easy to fix. I choose the latter. 99/100 times, when something breaks with an update, it's on the front page of archlinux.org with a fix.

The problems I've faced with other distros or windows is the solution is often "reinstall, lol", which is like a 3 hour session of nails on a chalkboard for me.

Before Arch that role belonged to Gentoo.

To add, before the change the Gentoo wiki was a top resource when it came to Linux questions. Even if you didn't use Gentoo you could find detailed information on how various parts of Linux worked.

One day the Gentoo wiki died. It got temporary mirrors quickly, but it took a long time to get up and working again. This left a huge opening for another wiki, the Arch wiki, to become the new top resource.

I suspect, for a number of reasons, Arch was always going to replace Gentoo as the "True Linux Explorer", but the wiki outage accelerated it.

I use Ubuntu professionally and Arch at home

Anything that's not Windows is my preference.

I love arch because I know what's in it and how to fix it and what to expect, the community is mostly very nice and open to help

AUR is great and using pacman feels lovely

I also care about learning and understanding the system I'm using beyond just using a GUI that does everything for me

Ubuntu is not bad it's probably one of the most used distros by far

Linux motto is: Use what you like and customize it how you like because there is no company forcing you to do things their way

It's funny because I see the same cult behavior, but for Fedora. I've never understood the point of this distribution that has never worked well for me.

I'm on Manjaro by the way, because I love everything about Arch except the release style.

Arch is amazing for what it is, hence the love. It’s what you make of it; by default there’s nothing and you design your own system from scratch. This leads to a very passionate and enthusiastic community who do great work for one another, for everybody’s benefit. Anything under the sun can be found in the AUR, the distro repos are fresh and reliable, and every issue that arises has a hundred people documenting the fix before it’s patched.

Ubuntu has a bad reputation for inconsistency, privacy invasive choices, etc. I don’t think all the hate is deserved, as they corrected course after the Amazon search fiasco, but I still won’t use it because of Snaps. They have a proprietary backend, so even if I wanted to put up with their other strange design decisions I can’t unless I wanted closed source repos. That goes against my whole philosophy and reasoning for being on Linux to begin with, and many feel the same.

Normal people who use Arch don't bring it up much, because they're all sick of the memes and are really, REALLY tired of immediately being called rude elitist neckbeard cultists every time they mention it.

The Ubuntu hate is because Canonical has a long history of making weird, controversial decisions that split the Linux community for no good reason.

I'm quite experienced in Linux but I wouldn't use either. Arch is great if you like to tinker, Ubuntu sucks for the not so libre approach , corporate ties, telemetry etc. I distrohopped before but today I just install my debian based distro and shit works.. Ubuntu I've installed twice before when I was new to Linux, and have had a major issues every time due to official updates that broke internet drivers and other things, that's a fun one when you only have one PC . Not to mention its so bloated that shitty computers that I like to thinker with it have a hard time catching up. The arch thing is also mostly a kind of meme, targeting the more unbearable nerds. People I hated when I was a noob (they will let you know you are) But they are found everywhere and in general I don't think there's more of those people in arch community than anywhere else. It's more of a stab at elitism than arch specifically.

I see a point in arch but zero in ubuntu.

Arch Hits the great spot

It has:
- a great wiki
- many packages, enough for anything you want to do
- its the only distros that is beetween everything done for you and gentoo-like fuck you.
- and the Memes.

the wiki ~~and forums~~ are the best of any distro

If you don't participate in it that is.
If you veer only a little off of their strict rules,
then Arch forum will ban you and they won't allow you to even read the forum.

because they used to be special. "I run linux", matrix text on boot, typing shit in the terminal, "I'm in", awe-inspiring shit to an onlooker...

but nowadays, anyone can run ubuntu or mint or whatevs and our hero ain't special no more. so here comes the ultimate delimiter.

Arch is better because...

• pacman, seriously, I don't hear enough of how great pacman is.
  Being able to search easily for files within a package is a godsend when some app refuses to work giving you an error message
  "lib_obscure.so.1 cannot be found".
  I haven't had such issues in a long time, but when I do, I don't have to worry about doing a ten hour search, if I'm lucky, for where this obscure library file is supposed to be located and in what package it should be part of.
• rolling release. Non-rolling Ubuntu half-year releases have broken my OS in the past around 33% of the time. And lots of apps in the past had essential updates I needed, but required me to wait 5 months for the OS to catch up.
• AUR. Some apps can't be found anywhere but AUR.
• Their wiki is the best of all Linuxes

The "cult" is mostly gushing over AUR.

"I run Arch btw" became a meme because until install scripts became commonplace you had to have a reasonable understanding of the terminal and ability to read and follow instructions to install Arch Linux to a usable state. "Look at my l33t skills."

Dislike of Ubuntu comes from Canonical...well...petting the cat backwards. They go against the grain a lot. They're increasingly corporate, they did a sketchy sponsorship thing with Amazon at one point, around ten years ago they were in the midst of this whole "Not Invented Here" thing; all tech had to be invented in-house, instead of systemd they made and abandoned Upstart, instead of working on Wayland they pissed away time on Mir, instead of Gnome or KDE they made Unity, and instead of APT they decided to build Snap. Which is the one they're still clinging to.

For desktop users there are a lot better distros than Ubuntu these days.

I left Ubuntu for Arch because I got sick of Arch having everything I wanted and Ubuntu taking ages to finally get it. I was tired of compiling shit all the time just to keep up to date.

Honestly glad I made the change, too. Arch has been so much better all around. Less bloat and far fewer problems.

I installed arch before there was the official install script. It's not that is was THAT difficult, but it does provide a great sense of accomplishment, you learn a lot, customize everything, and you literally only install things you know you want. (Fun story: I had to start over twice: the first time I forgot to install sudo, the second I forgot to install the package needed to have an internet connection)

All of this combined mean that the users have a sense of pride for being an arch user so they talk about it more that the rest. There is no pride in clicking your way though an installer that makes all the choices for you
