The biggest feature of Wayland for me is mixed refreshrate monitors works OOB. On X this is a pain to get even remotely working and it’s impossible if your monitors aren’t dividable (120/60 works, 144/60 stutters).
This is from my experience something that is starting to be a way more common issue (high refreshrate laptops with 60 external monitors at businesses or high refreshrate monitor for gaming and a smaller secondary monitor for info lookup/discord).
other than that, Xorg does win the “more stable” prize for me, but if I wanted stability, I should’ve become a carpenter.
Missing the joke here? We run a 3090 and a 3900x just fine on ArchLinux.
