Linux

NixOS because all the other ones differ about as much as Windows 10 from Windows 11. Guix doesn't count.

Fedora because I like this out of the box look more than Ubuntu and it runs my games well with my nvidia card

Primarily I use Arch on my desktop (and by proxy, my Steam Deck which runs SteamOS), which is what I've landed on after a ton of distro hopping. The idea of Atomic distros catches my eyes, but for me in its present state there are too many steps needed in order to make deeper changes (for example, installing a kernel module) - but I quite like SteamOS on my Deck since I know it will always be in a "consistent" state, for example.

On servers I run a mix of Rocky Linux and Debian.

Tuxedo OS. Same idea as smth like mint or PopOs but (imo) done much better. It also has rolling release for some stuff (like the DE) and non-rolling for other stuff (not even sure what bc I don't really look in detail). It also uses KDE plasma my favorite (and imo the best) DE. It's got pretty good app availability in terms of official packages because it is based on Ubuntu LTS (now 24.04). There are a couple things that are vestigial on most computers bc it was made for tuxedo computers but these have no negative effect on other devices in my experience.

Elementary OS.

I really like the focus on delivering a solid, intuitive and snappy desktop environment. It is absolutely what I recommend to newbies, who are looking for a Windows or macOS replacement.

Arch, cause I set it up to my liking once out of curiosity when I was procrastinating, wrote a script that automates https://wiki.archlinux.org/title/System_maintenance and now am too lazy to switch to something else.
Especially since maintenance involves typing Update.sh once a week or so, and nothing else.

I started with mint cinnamon and then tried out bazzite and nobara but they both gave me issues so I'm back to mint because it really does "just work"

My server is running mint currently, but I'm going to switch to fedora at some point soon. Mostly because I have to deal with RHEL at work and I'd like to better familiarize myself with it.

Fedora KDE, because my preferred distro Mint Cinnamon doesn't at the moment have good support for things like FreeSync.

elementary! I like it, been using it since ~2018, I like its style and I don’t mind reinstalling for major updates. They’re pretty seldom if you’re on the LTS branch anyway

Gentoo on my home computer. Started way back in the day when you had to recompile source RPMs on RPM-based distros to get CJK (Chinese, Japanese, Korean) language support. Debian language support was excellent, but I didn't enjoy always being 5 package versions behind, especially as fast as some software was being developed.

CJK isn't an issue anywhere anymore, but I stay on Gentoo because it has all the packages I want, and it doesn't force systemd on me.

Will be moving away from Ubuntu on my work computer because of all the foolishness with 'is it deb or is it snap?'. Not sure what I'll go to.

Ubuntu, because I'm fine with something that "just works"

Kubuntu on my desktop, I prefer KDE as a DE and I'm used to the Debian ecosystem.

Linux Mint on my relatively low powered laptop that I rarely use.

Debian stable on my media server.

Lubuntu

My first foray into unix-likes was oprnbsd with fluxbox. I eventually moved to openbox. Lubuntu with lxqt gives a nice simple openbox experience with a menu and stuff. I customize it to have openbox present the mouse menu instead of the whole pcmanfm desktop thing.

Arch on my desktop and laptop, Debian stable goes on everything else.

I've hopped distros alot and then just felt most comfortable with arch linux. I try other distros and then just go back to arch linux everytime. I just love the AUR and the utilities that are available to arch linux. The wiki is also very good.

Fedora. I like the rolling release but with large updates separated into point releases, as well as the ability to perform offline updates. I also like the preinstalled security stuff
