Plex & Sling rule, though depending on what Hulu liveTV is like when it comes out of beta -- that could change...
I'm still waiting for the true ala-carte service: 20 channels for $20, and I choose the channels -- premium services like HBO, Showtime, etc would be add-ons, but anything with commercials could be included in the 20-pak. Pipe-dreams are fun...
I only use Apple TV 4's on All 8 TV's. So the following can be used on all of them.
WatchAid - Universal Watch List. Initial App for most shows.
Hulu - TV Series with No Commercials
CBS All Access - TV Series with No Commercials
DirectNow - Live TV like News
Channels - Live TV and DVR (for Shows not on Hulu or CBS)
HBO Go - $5 with DirectNow.
Showtime Anytime - HomeLand and Movies. Add On with Hulu
Netflix - Original Series and Movies
Starz - Moves. Add On with DirectNow.
My favorite apps are my most used apps. WatchAid and QVC top the list. WatchAid is everything the TV app should've been. As for tv service apps I use Hulu and CBS All Access. Both are No Commercial plans. I also have Netflix.
I watch a ton of YouTube but I hate the app. So I feel conflicted about listing it. But I use it so much that I'm listing it anyway.
I don't game much on my tv because I prefer playing on my iPad mini and watching tv simultaneously. But if I had to choose I'd pick Asphalt 8.
