The previous Apple TV incarnations were not great, but the current Apple TV is fantastic.
If you need to access your own media, you can run an app such as Plex, Kodi or several of the other alternatives. I've only used Plex, which covers all of my needs.
With the current streaming offerings I'm increasingly less dependent on BitTorrent. Amazon Prime became available last year, but I especially appreciate niche players like FilmStruck (which has a small but rotating subset of the Criterion Collection) and Fandor.
