The drivers for gpus are a bit annoying but only if you want to game on Ubuntu.

Nouveau drivers are horrible for performance and the nvidia ones are not always great, if you can find a compatible one.

That being said - I can't compare with AMD as my last system of Linux with an AMD gpu for gaming was back when it was an ATI gpu. :p

I have two systems with AMD GPUs: a desktop with a 2015 R9 Nano and a 2018 Thinkpad with a Ryzen APU. The amdgpu driver works perfectly on both of them. The Ryzen APU has one issue where you need to set `iommu=soft` in the kernel parameters to get it to boot, but that seems to be more related to the CPU than the GPU.

I don't have that parameter set, everything works fine. Ryzen 2400G.

Maybe it's got to do with the chipset? Not sure, I don't have any other Ryzens to compare against. But `iommu=soft` is strictly required on my system, otherwise the screen just stays black after the boot manager.

nVidia's drivers cover a pretty wide swath of cards. I've had decent luck in Ubuntu just going to the proprietary drivers section and clicking on the binary blob. The only downside is that it locks you into one version of the driver until you do a full OS upgrade, and that driver gets pretty out of date by the time the next LTS is ready.
