Arch Linux. Always very up-to-date and the AUR is huge. No dealing with PPAs or snaps or flatpaks or appimages. Just paru -S any-software-ever-made. Also very streamlined (systemd for everything lol) and well documented. I tried NixOS for a bit but it was very inconvenient in comparison and I felt like it was impossible to tinker with or understand if you weren't good at Haskell. Terrible documentation.

For servers it's definitely Debian + docker.

Debian. Several reasons:

• It's trustworthy.
• It's not going anywhere. Debian existed when I was a kid and it'll probably still exist when I draw my last breath.
• I know how to use it, since, once again, I've been using it since I was a kid.
• It has all the desktop environments.
• It fully supports systemd. I do not miss the unreliability, slowness, and complexity of what came before that. (Normally I wouldn't mention this, but your former distro of choice exists solely for the purpose of not having systemd, so it's relevant this time.)

Fedora, because it just works and it ships recent software versions.

I also like Fedora Silverblue, and projects like ublue are very interesting in my opinion.

arch

NixOS everywhere (except for one server which I have yet to migrate from Rocky to NixOS)

I was a distro hopper once, then I saw the light of NixOS...

I use opensuse with kde and I love it. Have been using it for 2 years now.

For server use at home I use Ubuntu Server and Alma Linux (mostly)

At work it is all RedHat.

I use Arch Linux with KDE Plasma myself

I use Debian with a patched version of motif window manager. The 90s never ended:

Linux Mint with Mate DE.

Using Arch everywhere (home, work, laptop). It's boring, but it just works.

NixOS. Declarative config with opt-in state is awesome.

Linux Mint. Nothing beats your computer just working when you have shit to get done.

Arch on everything, including servers. It's just so easy to install everything via the AUR & configure everything easily. Plus the wiki is amazing. Although it is a pain to setup sometimes

I've been a daily fedora user for the half year. Initially I started off with ElementaryOS but it was so filled with bugs, and glitches, so it didnt last for more than a couple of months. While the fedora experience is way more streamlined.

Arch Linux everywhere. I'm curious about NixOS but I don't have the time to tinker anymore.

I used to use Void as my main distro, but then the developer drama made me shy away from it (keep in mind, this was like forever ago and I haven’t looked at Void at all since). After that I floated around trying everything, from Gentoo to the BSDs (I know, not Linux). Nowadays I use OpenSUSE Tumbleweed. I got tired of doing everything manually and OpenSUSE just makes everything so much easier to use, IMO.

I have a few dozen computers and most run Pop!_OS.

OpenSUSE Tumbleweed on my laptop, Debian on my server and SteamOS on the Steam Deck.

I used to use Debian but after switching to Fedora Silverblue two years ago I've had zero urge to distrohop. I love that it allows me to tinker without breaking my system (which I used to do with Debian).

Fedora on the desktop. I got my start on Red Hat Linux so I've stuck with it since.

For servers I use Debian. Lightweight, widely used, and gets the job done.

Mint with Cinnamon is my daily driver on my desktop and laptop for almost 3 years now. I ran a company for a while using Linux and managed to find everything I needed for software to run administration. It was great. I still have a windows tablet for troubleshooting and equipment specific requests, but I always feel weird logging into it.

Ubuntu for life. Unpopular opinion i know, please don't stone.

SUSE

Garuuuuuda. Love it. Been running it for the past few years. The devs come off as assholes, but they're actually just German;)

I'm currently using a mix of Arch and Fedora, but I've been starting to look in to NixOS.

At work we are mostly Rhel, so then at home I have some Rocky VMs and main system is Fedora. I used to run Arch, but then got lazy…

Endeavour OS. Been on it nearly for two years now.

Gnu guix

Been using NixOS for a couple months. It’s gotten easier to configure and change because of it, and new computers are super easy to setup because I can just change/apply the config and system wide changes will apply with one command!

I like to keep things somewhat basic so I use Arch btw....

I use NixOS for everything. I have a Nix flake that defines my systems (two VPS, a desktop, a laptop and a little home server) and I can modularize the config snippets that apply to the machines so I can effortlessly reuse them. Add to that the atomic updates and reliable rollback and there you have it.

OpenSUSE, Tumbleweed on workstations (KDE) and Leap on my server.

Switch from Windows to Fedora as my daily driver and for some gaming. Works flawlessly and I love every parts of it. Linux has such cool distros and communities

I just recently switched to Arch and I gotta say, the AUR is indispensible! Also really like how fast pacman is.

I use primarily Fedora for desktop/dual boot and minimal Rocky for server. I mess with Arch and Manjaro when I'm feeling adventurous.

Debian

I use NixOS on all of my servers.

Does SteamOS count? My steam deck is my current “Linux” machine.

A couple of them. At home my main distro for desktop and laptop is openSUSE Tumbleweed. I like it the most since it is a rolling release (with fresh and up-to-date software versions) and they actually have some CI/testing setup so they do some basic tests of packages before releasing them and it is thus one of the most stable rolling release distros. On top of that they also ahve a system setup so that a BTRFS snapshot is done before and after each update automatically and a GRUB boot entry is added. In this case if something would go wrong with the update you can always boot back into old system before the update. Also they have one of the best KDE Plasma integrations.

In addition to this I also use SteamOS (Arch-based) on the Steam Deck, PopOS on my work laptop (would use Kubuntu but that is what they forced us to standardise on), and one machine I have is still running Gentoo. All are runnign with KDE Plasma as a desktop.

Mostly NixOS unstable. I have one machine still on Arch, but i plan to switch that to NixOS too.

Manjaro. I am a guy of habits, so I never really distro-hopped, I once tried to install Arch and failed to configure everything so I tried endeavour and failed too (which would mean I am not a tech guy either ;). Ultimately, I'd say that the distribution does not matters much once you are used to it, you can always get what you want from any of them. The only thing I really like in comparison with others is pacman :)

I'm a opensuse tumbleweed user on my desktop and laptop. I also have an ubuntu home server.

I really like tumbleweed, but I have been thinking of switching to an immutable distro like guix or nix. I've tried guix several times and found it pretty good, but never stick with it due to its lack of KDE plasma support. Maybe I should give nix a try.

Hanna Montana Linux as my daily driver. Endeavouros for work.
