Roku Streaming Stick vs Apple TV 3?



Any thoughts on which streaming device to get? I know that both are good, but I want to get the best one that will get me the most streaming TV shows and movies.
Don't forget Amazon's Fire TV. However, "most streaming TV shows and movies" for now is probably Roku. Not sure if the Roku stick gives you everything the Roku 3 gives you, content-wise, but keep in mind it's slow and has to fully boot up each time you turn on your TV.
