Streaming is not the panacea for entertainment that providers want us think it is.
We've been Netflix subscribers for years. I started Prime a couple of years ago mostly for the shipping. We looked at their streaming and it pales in comparison to Netflix. Conversely Netflix only has about 30% of all available shows and movies available for streaming. The rest you have to get through their DVD/BluRay service. The reason for this is the cost of the content.
That said to cover those costs you can get more options with Prime, but you pay additional fees on top of the annual fee.
