I did some research a few months ago and what I found is that Netflix gives a better selection for your money. We are doing the free trial runs to get a feel for each one. Netflix and Amazon Prime will give a one month free trial.
So far, we are only using Netflix $8 for instant streaming along with Hulu's free instant TV shows. With an additional $8 a month we can order the latests DVDs through the mail, but we find it easier to use a Redbox. Here's one of the sites that did a comparison on Netflix, Hulu Plus, and Amazon Prime:

We are in our second month with Netflix and we have just started our first month with Amazon Prime. We agree Netflix is better.
