I use NVidia on my single Windows gaming system, but every Linux desktop system around here has AMD. I actually end up playing just about any game that plays on Linux on one of my Linux machines, and only boot the Windows system when wanting to play an exclusive title or occasionally just to do OS updates to be ready to play later. I've been using almost exclusively ATI/AMD GPUs since the Mach32 days, but for Windows gaming systems sometimes NVidia has the performance crown for months or years at a time with reasonable stability.
My fastest laptop is an oddball. It uses an AMD mobile processor with integrated graphics and an NVidia discrete GPU. Windows 10 handles that fine. Several Linux distros didn't install correctly at the time I bought it, but Ubuntu did. I'd have been okay with it installing to only support the integrated GPU, but it supports both and has a menu option for every app to launch it on the dedicated GPU. So far the only problem I've had with that whole laptop is a Windows update breaking the bootloader and making Linux temporarily inaccessible.
