Ok here is a bit of a rant
Fr, Especially on Arch based distros where the Aur (which is wayy better) exists + I don't use gnome I use Cinnamon(Gnome done right)
If you want Nvidia Reflex,DLSS and RTX and GSYNC,etc and your fine with installing out of tree proprietary drivers and fine with some minor issues(Like rarely breaking randomly) Nvidia
If you don't care about Nvidias features AMD.
X11 or xorg is old and dated and uses a "x server" to work which is what it manages what you see and stuff.
Wayland is new and updated removes the need for a server causing lower latency and faster composting but less compatible.
