I run Linux on everything, and have a system with nvidia card and one with AMD, so speaking from real experience rather than echo chamber regurgitation (which is definitely a problem in this space so good to be aware of it). I will go AMD every time for gaming and general dual/triple screen monitors. I would only go Nvidia if I needed CUDA (such as for machine learning).

If you need OpenCL or if you go Nvidia and need the proprietary driver, it will make distros like Fedora (my favorite), Arch, etc a lot more difficult as they stay very current on kernels (which is great for hardware compatibility). Nvidia is better than AMD in this regard if you need the AMD pro then you just won't be able to run Fedora. If you don't mind Ubuntu, then you'll be ok. It's well supported for Nvidia drivers and AMD Pro.

I have been amazed at how well everything "just works" with AMD on Fedora, and for that reason AMD is my default.
