AMD GPU support is excellent and built into the kernel, but i'd still hesitate to day 1 a newly released GPU, but I'd hesitate to day 1 a newly released GPU on windows too (and this is for amd, intel and nvidia)

nvidia is more of a headache, but a lot of distros have nvidia specific packs so you don't have to deal with the nvidia driver headache yourself, but not entirely perfect.

Intel is still developing its drivers, some updates seeing some big gains.. But theres also concern of intel going Ouroboros in the whole "We're releasing a new product, but its not selling as much as we want due to our history of cancelling products early causing consumer hesitation, so we're cancelling this product early because of consumer hesitation" and intel owners being left in a lurch of abandoned products.

Personally, I would get an AMD gpu. not out of some weird parasocial obsession with a multi-billion dollar company, but simply because its the most easy, best supported, most plug-n-play gpu to use on linux
