NixOS on two boxes (starting to deep dive big into flakes to try to automate how the separate devices are configured and apps installed, it’s pretty slick if you ever need to reload the PCs). I have endeavorOS for an AI test box since it was easier to get an arch based distro to work with the complicated install chain of Cuda and Python dependency hell. I have Fedora on an PC my wife uses with Budgie. I have a Debian box for my 3d printer controlling. I may move something back to Solus once they release their new ISO, I miss it. I’d probably end up installing nixpkgs on it so I don’t loose too much functionality/package availability.

Nobara on the Desktop, Pop OS on the Laptop and the Surface (needs a custom kernel though). I'd use Nobara on everything but I am too lazy to switch.

Fedora with KDE!

Gentoo is my prefered distro.

Arch

I'm a Trisquel user. Though, I'm thinking of moving to Guix.

Arch w/ XFCE

I've been maining endeavouros for a little over a year now. It's oddly easier than any other os I've ever run.

Debian since '95, (After a try with Slackware and RedHat each for a month or 2-3)

I run testing on my home devices (trixie now). Totally happy with it. (I really don't like the rpm based ones, even more so since IBM bought RedHat) Tried Ubuntu once, didn't know how fast to get back after the 1st major upgrade killed my system years ago.

I used ctwm since '96, switched to xfce4 in '18 (and use it as wm), ctwm is still in use for vnc connections on the rpi.

Arch as a daily driver, Debian for my girlfriend and the self hosted stuff, Raspbian for the PiHole

Fedora because they keep the packages updated. I could go with Arch, but the amount of updates per day is too high.

Fedora, it’s running great on my older ThinkPad

Mint, yet on my old laptop. Still on Windows on my main PC

The one that works for my use case.

Fedora Workstation
