An AMD GPU has been less work for me running Linux (Kubuntu at the moment). The nvidia card worked fine, but I had to manually update drivers about every week. Had games I was trying to run complain whenever drivers were not the most current version. I now have an AMD card, popped it in, everything works with no hassles. I’ve built my own systems for decades, but now would probably recommend buying a pre-built. It’s fun to do, but there aren’t really any cost savings doing it now.

I enjoy a good bit of linux. Heard that amd stuff usually plays nicer with it although I don’t know enough to consider it a fact.

It’s true that AMD GPUs play nicer with Linux than Nvidia does, mainly because of the open-source and well integrated driver stack.

My advice is usually to choose AMD graphics (or maybe Intel if your games allow it) for new purchases, but to keep using any Nvidia card you already have until it’s time to replace it (with AMD).
