Linux

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

Fedora.

I've tried them all but found it's the most reliable. It's upgrades are even more reliable than Macos and Windows.

Packages are very up to date but also well tested. Sometimes even newer than Arch for short periods.

The community is awesome.

I love Gnome, I've found it's more consistent than even MacOs in its design. And it has perfect keyboard shortcuts.

Void because I don't like gnome, primarily because it uses more than 50% of my resources, so I need something lightweight and have had bad experience with arch. I've had some hiccups with void but it wasn't something I couldn't fix. The downside is that it there are no package repository mirrors in my region, and sometimes I have to change mirrors to install packages, and some applications are not packages for void, so I have to look for open source alternatives that I have to compile.

I use TuxedoOS. I wanted something that kept up with the latest KDE updates which ran a cleaned up version of Ubuntu... that's TuxedoOS to a T. I had looked at other options like Kubuntu or just installing KDE over something like PopOS, but TuxedoOS was the most stable and up to date of those options in my testing.

That said, I have run into innumerable problems on it due to apt repos that it doesn't include which come standard on Ubuntu.

Debian Testing (laptop, workstation and RPIs) since it works best for me. Tried Gentoo, Arch, OpenSUSE and several others. Also, I've been using FreeBSD for some time.

Arch.

Because of pacman. Building and writing packages is simple and dependencies are slim. Also packages are recent. And most likely "there is an AUR package for that". Also stack transitions arrive early, like pipewire.

Also let's not forget Arch Wiki, i bet you have read it as a non Arch user.

I administer Arch on 8 machines including gaming rigs, home server, web server, kids laptop, wifes gaming desktop, audio workstation and machine learning rig and a bunch of dev laptops. I also use ArchARM on RPi for some home automation.

Never considered switching since I switched from Ubuntu over 15 years ago.

I do have experience with several other rpm and apt based distros.

Guix SD because i like editing declarative ((`scheme)) config for my system in emacs

I've been using Bazzite for a few months now (switched from EndeavourOS, which was great) and it's been amazing. I'm sold on atomic/immutable. I have never had a PC this stable, including every Windows PC I've had.

And it's perfect for gaming. There are weird little tweaks and settings that I had to do on EOS to get my GPU working correctly, etc., and they all just work out of the box in Bazzite (I did get the iso image made specifically for my laptop, which definitely helps). It's super impressive actually.

And distrobox (BoxBuddy comes installed) can be used to access the AUR or whatever if I feel the need to. Just fire up an Arch box, and have at it.

Arch. I need the AUR for certain applications, and the high degree of customizability and opportunity for learning appeal to me as a relatively new-ish Linux user (going on a few years now, most of that time having been on Arch).

Because the logo is cool :)

I use NixOS for my desktop because ~~I hate myself~~ you can configure everything without needing to edit a bunch of different config files that use different configuration languages.

I use Arch btw for my Minecraft server because I am crazy.

btw i use Arch, i use it because i found lot less effort it takes to do anything and it's stable, i do think there is some bug with QTcreator, gotta see it's os issue or QT issue.

Endeavour OS because once you go rolling you can never go back.

Mint for my desktop system. It just does exactly what I want it to, has good compatibility with software and Cinnamon is my DE of choice.

NixOS for my server, because being able to use one config repo and format for everything is so nice.
