Windows 10 for now. When they EoL it I'll switch to a Linux distro. Not sure what yet. I really like PopOS on my Surface because the gnome interface works well, but I think I'll go with something built with KDE for my desktop
Tbh I prefer something easy because I'm lazy, but I'm perfectly comfortable with something that requires tinkering. Had to do plenty of that on my Proxmox homelab
I'm in the same boat as you. Don't like where Windows is going so I'm going to try to switch before 11 gets forced on me.
I've got Fedora KDE Spin on a mini PC that I am trying to use as a workstation while my main Win10 PC handles gaming. I have a Steam Deck so I know I can do a large majority of my games on Linux, but I'll probably have to figure out a dual boot or virtualized thing of some sort for the titles that don't.
I've got a few years to figure it out before Win10 stops getting security updates.
