The drivers have gotten a lot better over the last few years, and Nvidia even have an official open-source driver now, but there’s still issues with them. Wayland works very well now, but not perfectly (especially on GPUs with low VRAM).
If you’re on Linux and are buying a new GPU, stick to AMD. Their driver is part of the Linux kernel, it’s more stable, and it gets all the newest features first.
