I recently moved from win 10 to Pop os for work related stuff, also I have arch on another ,free time pc, and Mint on my old home server-ish pc.
Pop is pretty good, all necessary stuff is preinstalled, I like how it works out of the box. Games run smoothly, not as smooth as on win but I can give up 5 fps for not being MS(lave)
Mint has more preinstalled packages, feels more bulky but runs ,smoother, on old laptop. Also the ui is more like windows
Xiaomi will make Your data opensource.
If there is product like this (foss based, no cloud) i want to know too
