Well being from Canada not sure if the rules are different (I heard they were) in the USA but i use Kodi/android box.
Its a great way of streaming and collecting all the links into one area to watch movies,shows or even live tv and sports.
I don't have cable anymore, so it's mostly Hulu for me. I haven't been liking Netflix as much lately... they're getting too focused on their crappy originals to put other stuff on there.
Also, I sometimes use sites like Dailymotion for new(er) cartoons, since there's a lot of that type of stuff on there.
I mainly watch YouTube actually, since it's all free and has a lot of good stuff if you know where to look.
