I can't speak on behalf of the other apps, but I do have HULU and Netflix.
HULU is pretty good and has recent shows that just aired for some major networks. You do have to watch adds every 15 minutes. That doesn't bother me though because the adds are only about a minute long at max.
Netflix is ok. It has tons of movies but only releases a few newer movies online for streaming video.
I am not %100 sure but I think they both have a free two week free trial so you can test them out. Just be sure to remember to cancel your subscription if you don't want it.
