I actually posted this very question at the beginning of the year when I was in the market and got the same varied responses on which was better.
I went to the Apple store to look at them and they quickly told me they would match the Best Buy price and then she asked if I was a student, I was honest and told her not for about 3 years or so, she still gave me the student discount on both the rMBP and Applecare. It was the easiest buying experience i have had in a store, they took the time to show me how to use it (was a first time mac user) even though they were slammed.
