Right now Nobara (Fedora based) on my gaming laptop but was curious about Endeavor and planned on testing it out on a POS slim client from 2012 that I just got. Steam deck just has stock SteamOS.
My main desktop is still windows because I play CoD warzone a lot with friends and that’s still a complete non factor for ricochet anticheat but if they fixed that I’d probably move off of it entirely assuming i could get my peripherals/davinci resolve/stream Labs/oceanaudio all working and get used to GIMP/Krita instead of Paint3D.
So yeah there’s a few reasons I stick with windows, plus I like to keep up to date since I work IT networking and we are a windows shop primarily.
