apple tv 4K is AWESOME, I just switched to it literally days ago. Its the best set up I have ever used. Never used a PC but used my iphone, ipad and a surface at one point and the apple tv is my favorite.
ONLY negative IMO is the remote. Its....touchy, once you get used to it its fine but it could be better. But you can you the companion app on your phone instead and that is pretty straight forward too. You will love apple tv, its simple and really easy to start up. Its just great IMO.
