I don't use either now. I have tried both. When I started with Ubuntu i was great; fast, light, all the good stuff. Then it started to get bloated and wouldn't run on my old machine... So I moved to Arch and it saved me and I used it for years.

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

Anything really polarizing can end up with a cult following. Just look at Rust.

Because there are still people who have not yet seen the light. Once everyone has joined the fold they will not be able to remember why anyone resisted in the first place.

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.

People praising Arch, people hating on Ubuntu, meanwhile me on Debian satisifed with the minimalism.

People making the things they consume their whole personality, not a rare thing tbh.

I've started with ubuntu/mint and it was always a matter of time before something broke then i tried everything from then all the major distros and found that I loved being on a rolling release with openSUSE Tubleweed (gaming and most new software works better) and BTRFS on Fedora (BTRFS let's you have boot time snapshots you can go back to if anything breaks).

After some research I found I can get both with arch so installed arch as a learning process via the outstanding wiki and have never looked back. Nowadays I just install endevourOS because it's just an arch distro with easy BTRFS setup and easy gui installer was almost exactly like my custom arch cofigs and it uses official arch repos so you update just like arch (unlike manjaro). It's been more stable than windows 10 for me.

Tldr: arch let's you pick exactly what you want in a distro and is updated with the latest software something important if you game with nvidia GPU for example.

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.

People that got into Linux when most of the main distributions were easier to install than windows in most cases. Some people wanted to show off that they can install a Linux like it was when we did it back in the 90s for some reason I still don't understand till this day. I do like their wiki though. Works great for debian as well as arch.

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.

Because the logo looks cool

Because it just works. I used to love Debian . It had issues with drivers and stuff. Arch just does it for me.

Slackware users, "Those Arch users are crazy."

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 can't speak to Arch but I use Ubuntu every day. I hate on Ubuntu because I use it every day. They make terrible choices. They've got common, serious issues people have reported at least as far back as 2009 with no acknowledgement or plan to address. I'm on LTS and they push through multiple reboot requiring sets of updates a week, heedless of the impacts.

I don't feel like learning a totally new environment so I'll be switching my main computer to Mint whenever I get the time. So I can deal with someone else's annoying decisions for a while.

I feel like it isn't really specific to arch, every distro has a following, but some are more "passionate" about it than others. I think arch, NixOS, and gentoo are the most notable.

Because Arch requires human sacrifice.
