Netflix or Blockbuster?

Does anyone out there reading subscribe to one or the other? My friends Kara and Chrissy both love Netflix, so I was all set to sign up until The Mister's friend tossed in his two cents on his Blockbuster. I don't know all the technicalities, but you can rent online just like Netflix and then pick up an additional movies in the store--and somehow you get those additional movies wind up being free if you cost compare.

That didn't make any sense. Let me try that again. The Mister's friend says Blockbuster is cheaper and more convenient than Netflix. Now we're writing in English!

Anyway, failed attempts at communication aside, do you have a preference?
