I use Netflix, my dad changed us over after he had a bad problem with it, and then he got really bad customer service on the phone he got fed up with it and changed us. With blockbuster it seemed slower to me, and Netflix has better descriptions so I would say Netflix. Plus, blockbuster gave us a ton of scratched disks and we had to send them back for a replacement, but that only happened a few times with Netflix. Oh, and Slipsoccer he means the online services for both of them
