The second gen 4K AppleTV works very well. It is slightly faster and can use FaceTime. Just another option if you buy used.

I could have had the M1 instead. I think back to that decision and shake my head. I was worried the M1 might not be compatible with my software.

I would say 2020. I made the mistake of getting an Intel over the M1. It seemed good to start but it seems very aged already and gets hot. My wife’s M2 Air is a lot better.
