We watch both Netflix & Amazon Prime at the house through a Wii (living room) & a Roku 2 (bedroom).In terms of ease of search & navigation, Netflix has a slight edge over Prime, although Amazon compensates for it with the "Customers Also Watched" option. The "Watch Trailer" feature is also nice...provided that it actually shows a "trailer" (note to Amazon: showing me a random 2-minute excerpt from within the movie itself, especially in the middle of the opening credits, is NOT showing me a trailer that gives me the basic plot of the movie & helps me decide to watch it or not).There are 2 major areas, though, where Amazon's video streaming is truly lacking compared to Netflix:1. *Rating the movie/TV show*. Netflix shows the average rating that other users have given a movie, but then lets you give it your own rating. Not only does it give their recommendation algorithm extra data to work with, it helps remind you if you've seen a movie before (especially if it hasn't been in your queue for months, or if it's one of those movie selections that was available for a while, was withdrawn from their library for a time, & is now back in). Amazon, however, doesn't let you rate a movie after you watch it. Not sure if they only allow those customers that actually buy the movie to rate it or not, but it would be a really nice feature to have.2. *Load & streaming times*. Yes, occasionally Netflix will have a "buffering" issue... but it's extremely few & far between. Amazon, however, has been very glitchy for the past month -- on both my Wii & my Roku, & at different times of the day -- where it will say it "can't connect"... even though it just did to show me the description of the movie itself (!!!) &/or the list of all the available episodes for that show. And even when it's not being "glitchy", it takes significantly longer to queue up a show than Netflix (usually about twice as long), on both devices.
