Just switched to Qubes and it has made me a Fedora user.

CachyOS (Arch based)

Slackware. As long as Pat keeps giving it away.

I currently use ubuntu, but I will try omarchy next.

Fedora sway atomic
Customized a bit to decrease memory usage. But besides that works very well out of the box. Toolbox on Fedora atomic is convenient also. I highly recommend.
I have been using KDE for many years but got tired by how the temperature of my laptop can get high with it. With Sway, CPU and memory usage, temperature are very low. No 3d bling bling compositor.

Pop os

Linux Mint

Ubuntu

Arch, btw.

Since my last round of distro hopping I settled on Fedora KDE as my daily driver on all devices.

Used Ubuntu Cinnamon before on desktop and Lubuntu on laptop.

No complaints so far. I gotta say I really like the idea of Omarchy for it's aesthetic, assumed opinionated choices and team, but sadly it's a bit too bloated out of the box for me and doesn't hit all my requirements.

It looks amazing for someone coming fresh from windows or macos though. Best effort to bring forth the mythical year of the Linux desktop in a while.

Ubuntu

I'm generally working on two systems; one with Ubuntu and the other with Zorin. I use Debian for my server and travel laptop.

So glad I over invested on RAM to play around with llm models early. It's all crazy expensive now. I use Ubuntu mostly, and occasionally Debian.
