My current experience on alder lake + Nvidia 30 series isn't quite a smooth enough experience to move my non-technical fiancee over, but it's close enough that I've considered it. The AMD drivers are mainlined and they've gotten a lot better about stability than where they were a couple years ago. Valve has done a lot of compatibility testing/fixes for the steamdeck as well. The Nvidia drivers are also pretty stable and many distros provide them out of the box. They're still going to be your main choice for ML stuff. For CPUs both Intel and AMD are extremely well supported. There are generally more eyes on the Intel side though.
