what's better blockbuster online rentals or netflix rentals

I've only used Blockbuster in-store and Netflix. For about a month in order to choose, we had both subscriptions and we found out that Netflix was a better deal in terms of cost and also convenience. Between seasons of shows we had 5 or 6 dvd coming at a time, but now in the middle of prime time we have cut it down to 3. We also stream instant tv shows from Hulu and other instant netflix plus feeds from CBS, ABC, and NBC via Play-on. I THINK Blockbuster is more expensive than Netflix, but I think they have about the same service other than that. I'm not sure though. Netflix has thousands of choices including instant, does Blockbuster have instant? Netflix is also very fast, the turnaround is about two days from when you send something back to when you get another movie - as long as your queue is full and there's no wait times on what you have in it.

I dont know because I havent used netflix, but I use to rent videos but I dont rent so much any more, I prefer to just buy my movies so I dont have to worry about returning them and I dont have to pay any monthly fees after I buy a DVD, and I can watch it as many times as I want.
