I am thinking about joining one of these two. They are basically the same price, so is there any reason to pick one over the other? I thought Blockbuster would get the edge since you can exchange movies in store, but I saw they charge extra for that so no thanks. Thoughts?

I'm thinking you should use the right forum Please check out the Store Forum for several discussion about this (and the two services individually), in particular this thread http://forum.dvdtalk.com/showthread.php?t=506814
