> I have recently switched from an NVIDIA Quadro card to an AMD FirePro card. I use GNOME/Wayland and the difference is quite big, with NVIDIA on nouveau, there was regularly flickering (at random moments), artifacts and other problems.

nouveau was always pretty awful, but the nvidia binary drivers always Just Worked, across many models for many years, whereas with AMD it's always been a crapshoot whether a given card would work properly or not.

The binary drivers always kept up with the important things (indeed they were well ahead of AMD in terms of doing accelerated video decoding on linux via Xvmc and later vaapi, their xinerama integration was always better...). Sure, they don't support Wayland, but that's a solution in search of a problem; if and when there's actual value to be had by using it I have confidence that nvidia will support it.
