> I use Linux and have learned not to touch AMD GPUs
The situation completely changed with the introduction of the AMDGPU drivers integrated into the kernel. This was like 10 years ago.
Before then the AMD driver situation on Linux was atrocious. The open source drivers performed so bad you'd get better performance out of Intel integrated graphics than an expensive AMD GPU, and their closed source drivers were so poorly updated you'd have to downgrade the entire world for the rest of your software to be compatible. At that time Nvidia was clearly ahead, even though the driver needs to be updated separately and they invented their own versions of some stuff.
With the introduction of AMDGPU and the years after that everything changed. AMD GPUs now worked great without any effort, while Nvidia's tendency to invent their own things really started grating. Much of the world started moving to Wayland, but Nvidia refused to support some important common standards. Those that really wanted their stuff to work on Nvidia had to introduce entirely separate code paths for it, while other parts of the landscape refused to do so. This started improving again a few years ago, but I'm not aware of the current state because I now only use Intel and AMD hardware.
