Someone give me a quick run down on AMD vs Nvidia on Linux

I understand that AMD drivers are open source and less of a hassle to work compared to Nvidia. But what else? What model should I look for? I don’t care for raytracing or other dumb gimmicks. Just want to run my map games and cowboy games without lag and crashes. Upscaling compatible is preferred in case I want to play newer slop without buying a new card.
