NixOS because all the other ones differ about as much as Windows 10 from Windows 11. Guix doesn't count.
Nix because I have a bad memory and hate doing things more than once
Alpine Linux. It's pretty lightweight (uses ~250MiB on idle with sway), is easy to install and is super stable. My only criticism is that there is quite a lot of software not available in the repos, but this is mainly fixed by flatpaks.
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.
Kubuntu, because it's the most solid distro I've used that meets my needs.
Fedora 41 KDE Plasma
For the simple, shallow reason it looks great and feels snappy.
Personal rabble:
spoiler
I would say that it does not feel as "set and forget" as Mint, but I enjoy the feel of of environment.
I am pretty new at Linux in general - only have experience with a Mint environment before.
I did have some issues with Fedora - mostly audio problems in Steam games and it can feel slightly more intimidating to work with ( compared to Mint) but after digging into various help threads and trying stuff( responsibly) I did reach a point where I reached a satisfied conclusion - even if I am not sure what exactly I did that solved the problem
Arch on my desktop and laptop, Debian stable goes on everything else.
Cachyos.
Used to use pure arch but I like the cachy optimisations and their repos
You can put Cachyos tweaks kernels and repos on top of arch or nixos if you like.
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.
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.
Mint, first one I tried, and works just fine. It's xfce with i3wm.
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.
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.
I like Manjaro
Artix because I love Arch and the AUR but networkd kept causing my home network to act like the mad hatter's tea party with IP assignment.
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
