This may start a war in the replies, but let’s see!
Arch btw
I’m boring Af, I use Ubuntu with Mate DE.
I would love to switch to Opensuse Tumbleweed, but I need Ubuntu because of some interactive board drivers that are only available for ubuntu… 😭
Fedora. Cause it’s the distro of choice of my employer and I’m just lazy.
EndevourOS, running gnome and x11 for better gaming performance.
I run about an equal number of Slackware and FreeBSD boxen.
Debian since 1.1
Arch as a daily driver, Debian for my girlfriend and the self hosted stuff, Raspbian for the PiHole
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.
I use Arch btw.
Steam os if this counts
The games are running smoothly? Even the heavy ones?
Fedora because they keep the packages updated. I could go with Arch, but the amount of updates per day is too high.
Manjaro
Currently Endeavour OS, but I mainly daily drive Fedora, because its the right mix between bleeding edge and stable (stableedge?) for me.
I’ve been maining endeavouros for a little over a year now. It’s oddly easier than any other os I’ve ever run.
