I've used the official nVidia drivers, they definitely don't work well compared to AMD/Intel on Linux. They're usable and more or less stable, but on my computer I was seeing stuff like window contents freezing, graphics stuttering, screen tearing on video playback, the mouse cursor lagging when there was high CPU usage, etc. and it all went away when I switched to an AMD card. Everyone I've talked to has has the same experience: weird performance hiccups or glitches that go away as soon as you stop using nVidia.
I've used the official Nvidia drivers on Linux for 5 years now and had excellent performance and few or no graphical glitches, with most issues coming early on. None within the last 2 years. Never experienced high CPU or freezing.
My cards have been a 2080, 3070 Ti, 4070M, and 4090. I could barely get an AMD card (6600 or something?) to work.
Now you have talked to someone who has not had that experience. And everyone I have talked to says they have had an experience either like mine, or like mine minus issues with AMD.
Performance is good but there are a few caveats. Namely dx12 perf (identified and being worked on), vram limit stutter (doesn't page to system memory well), HDR enabling requiring basically a hack because Nvidia doesn't want to implement color managent wayland uses, and some other annoyances.
