Which is better, the new, 2012 Netflix or the new, 2012 Blockkbuster?

I had a Netflix account for about two years. At first, we could get one movie at a time by mail for $9/month. After a while online “streaming” was added, and the price went to $10 per month for both services. It was great. When they suddenly raised the price to $17 per month, I put my account on hold, partially as protest and partially because I really didn’t need it. It is almost time to reinstate the account.
Now I see Blockbuster is advertising a package at $10 per month but I’m not sure of the details. (It is hard to tell.)
Since competition is what makes the world go ‘round, which service should I choose, Blockbiuster or Netflix?
I see this question was asked in 2009 and 2009. A lot has changed since then.
