I still have one of the Apple TV HDs from 2015 on one tv and it’s still fast compared to the built in smart tv on TVs I got last year. I had 2 more that I upgraded to 4K units last year but gave the HDs away and they’re still being used. They really weren’t expensive for me because directv had launched their streaming service and were giving Apple TVs away when paying for a certain amount of months.
