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.

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