Why do some reviewers say Netflix is better for TV, but Amazon is for movies now?

I notice VERY little difference between the two with movies, although it is true that Netflix is clearly superior with TV shows. Amazon does have the annoying thing where they try to get you to buy every other non-Prime movie or show they can. I have Amazon because I got a free year of it with the prime phone but I really don't use it a lot. I'll probably see 'The Wire' at some point because I am too lazy to download HBO GO, but besides that I have very minimal use for it, except 'The Man in the High Castle' is good and I'll see the full series when they release it. Sure you get stuff like prime shipping and other perks, but the streaming service itself is not superior or equal... yet anyway.
