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.)

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

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

Slackware

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

Linux Mint with Mate DE.

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

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

Debian 12 for now is a great investment for the next 5 years, tho.

Arch baybeeee 💯💯💯

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

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.

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

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 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.
