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.)

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.

Linux Mint with Mate DE.

arch

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

I use Arch Linux with KDE Plasma myself

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.

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’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.

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

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

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.

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.

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!

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 :)
