From a FOSS standpoint, AMD is clearly better since Nvidia doesn’t provide an open source driver and actively prevents one from being developed (that is feature complete) by anyone else.
From a gaming standpoint, I don’t think it makes much difference either way. Both companies make cards and have drivers that work very well for Linux gaming. Nvidia are usually a bit faster at supporting new cards on Linux, but that only matters if you are buying a card right at launch.
The main sticking point is Wayland vs Xorg. While you CAN use an Nvidia card for Wayland at this point, you are likely to run into some issues and it won’t be as nice of an experience as AMD. Nvidia will probably fully support Wayland eventually, but there is no guarantee.
Finally, if you need CUDA you just go with Nvidia.
It really comes down to your exact needs and how much you care about open source software as a principle.
