Nvidia just requires installing one extra package... It hasn't been an issue for a while now.

The nvidia driver actually works very well... The amdgpu driver wprks well but still has issues with suspend/hibernate. I'd say they are about the same IMO.

Except for Wayland, and KDE stuttering. I have an AMD and an Nvidia PC, both running Manjaro. AMD is really much less problematic than Nvidia for Linux.

Only if it is a recent generation AMD card.

Good luck with older cards, ignored by the open source driver.

A lot harder meaning: knows hot to install a program on Linux if the distro of choice doesn't outright ask to install the correct driver.

No, I mean specifically things like Optimus on dual GPU laptops. Also, even if the distros do in fact either install automatically or provide a method to install it, there is simply no need to even do this on an AMD system. And then there's the matter of AMDGPU being complete open source, while Nvidia's offering is not. And don't even start on Nvidia's slow pace to properly support Wayland.

There's the never let your GPU get old too. But since this is about gaming, it isn't very relevant.
