Here's my two cents... I am a fourth year student applying for residency as we speak (not at either school, but a VA native, and went to college in VA)... so I've been around the block and seen what impact the medical school really has...
If you have to decide between two schools, you need to take just a few things into consideration.
1) $$$$ If going to one school is $25k a year, versus 10k a year, that should be a no brainer. You will be just as educated at each place, one will not make you a better physician. Go for whatever is cheaper. Obviously, if they're pretty comparable, this goes out the window.
2) Where do you want to live for 2+ years? Granted some schools may let you do your 3rd year cores somewhere else, but you will likely be in the same area for atleast 3 years. Do you want to live in an urban environment or a suburban/rural college town? I went to FL for medical school. You simply can't beat that... I wanted to experience medical school on the beach...
3) If you believe you want to go into a more competitive arena of medicine (neurosurg, ortho, optho, etc), then your best bet is to go for the prestige. If you know in your heart that you want to do peds or FP, then it doesn't matter. Going to a nicer school CAN (emphasized CAN and not DOES) help down the road...
The first two years of medical school, which really are the ONLY differences between schools at all, really don't add up to much. You take the same stuff, you are exposed to the same things, you are taught the same way to listen to a heart, etc... once you get near the end of medical school and are applying for residencies, you'll realize that the stuff you worried about in re: to picking the school, or the perceived difference in the schools really amount to very little in the end.
