Hulu with no commercials. The bulk of my TV Series is still on Network TV. I get 1 or 2 good shows on the others but not as much as Network TV. I can get good movies on multiple. Amazon Prime is not on Apple TV so that rules it out.
The answer to this question depends on what services you already have. If you are a cord cutter with little or no access to broadcast TV; Hulu is your likely choice. If you still have cable or OTA access to network television, then Netflix or Amazon are your likely choices.
I presently have all three. I rarely use Amazon Prime and only signed up for Hulu for the 11.22.63 mini-series.
For me, the answer is netflix by a mile. The reason is on all formats (for me, iPhone, iPad and computer) their user interface is MUCH better. Amazon comes in second and Hulu is just beyond stupid and frustrating. It was the worst in userfriendliness in the old days and is still stupid after a revamp. They just don't get it.
Netflix is the one I reccomend. Amazon Video comes attached to my must-have Prime membership, so that's their main plus.
I have all three, I find my wife and I primarily use Hulu (no commercials) and watch an occasional iTunes Movie or TV series that's otherwise unavailable. We used to just turn on one streaming service, binge watch, turn it off, select another, repeat but I got lazy in cancelling. I guess that's part of their business model. =) All of them have shows worth watching, sometimes finding them is another story.
Changed my vote. Originally it was NF but since they only care about stupid original content most I have zero interest in and they took away just about everything else I loved about the service I now choose Hulu and second Amazon Prime Video.
We cut the cord last year. Currently, we have OTA channels which include the four major networks plus about 15-20 other stations. We also have Hulu commercial free and Amazon. I voted Amazon because it provides more than enough content plus the other added benefits, but Hulu commercial free is great also!
