Primarily use AMD graphics. My key issue on linux is the GPU reset situation, which can make experiences like VFIO and LookingGlass less than optimal, though there seems to be some commitment from all IHVs to improve desktop expeirence under Linux.
AMD and Valve work fairly closely on such endeavours which is neat, though we also have nvidia getting their shit together for Wayland and now offering an open kernel module (even in lieu of open, first party UMDs, for which the NVK driver is well worth investigating).
The open kernel module and NVK driver are applicable to Turing (your current GPU) and newer. Check them out.
You don’t owe it to anybody to align to a given vendor, just use what works best for you at a price point that doesn’t suck. If there are any specific use cases you’d like to know about then I’m sure the people here would be happy to test and report back.
