amdgpu is not a stopgap driver. It's mature and reliable enough driver to play videogames including a lot of windows games via proton. I don't see a single reason to use a proprietary OS or driver anymore.
As long as you don't have a funky setup, sure, but I've never been able to get AMD cards properly working for what I wanted to do (dual GPU setup, AMF on Linux, and multi-virtual monitors, ie 2 simultanious display on 1 monitor, or even getting the proper resolution from monitor behind an hdmi demux) , both with the opensource `amdgpu` AND the proprietary Linux drivers.
