I don't know all that much about any of these schools, but I just like to offer up some advice. When thinking about choosing schools, it seems that a lot of people tend to focus on aspects of the preclinical years. While those are important, I think it is more important to ascertain the quality of the clinical training.
For instance, how nice the anatomy lab is doesn't really matter in the end. Things like this don't really matter when it comes to how solid of a physician you will be when you leave medical school. You want to go somewhere that has excellent clinical opportunities, the funding for clinical/bench research and international experience, early clinical exposure (if you are into that sort of thing), excellent teaching hospitals, and a solid residency program where the residents have a reputation for being excellent teachers. The majority of what you learn (in terms of knowledge and experience necessary to the practice of medicine) will happen on the wards. So, I'd do some homework, make some phone calls, talk to FOURTH years, and talk with residents (if possible) about their opinions of the clinical nature of their program.
Things I'd think about when considering aspects of the preclinical years are:
1. early clinical exposure - This is a great thing! Interviewing and examining patients as a first year medicine starts the ball rolling that much earlier. Learning how to write up notes early on in your training will help you a lot and prepare you for third year a little better.
2. style of curriculum - It is hard to say exactly what style fits you best until you have tried all of them, but most people tend to have a hunch. Do you like lots of lecture? Do you like being tested on only one subject at a time? Do you like integration (organ-based) of many subjects? Do you like small groups and problem-based learning? Do you like Pass/Fail, or things like H/HP/P/F which actually equal A/B/C/F? Write down the things you want in a curriculum and then figure out which school comes closest to your priorities.
3. the administration - are they flexible? are they receptive to student input? This one is VERY important - are their opportunities to shadow physicians and be mentored?
4. duration - my program has us starting on the wards in April of our second year (also means we take the boards in April too!) this gives us a longer fourth year where we can take vacation, do away-rotations, have international experiences, etc.
Some other things to consider: location, cost (financial aid), history of graduates matching, and whatever else you can think of.
Basically, it comes down to a very personal experience. But in thinking about what medical school will give you the most opportunities, it is most important to determine which one is the strongest clinically (assuming you want to practice when you are done). Anatomy labs are important to consider, but in the longrun that factors in for a very limited amount of time while in medical school.
