Agree with using MSAR for this.
However, you'll find once you get into medical school that despite how they all try to "sell" themselves by emphasizing certain angles, most medical schools are very, very much alike in terms of what they end up teaching you. This is because what they are required to teach you is very much standardized. Also, you'll find that despite the mission statements of certain schools, a lot of the student have their own ideas about what they want to do and that may not jive with what the school says it is trying to do (i.e. lots of students at supposedly primary care focused schools want to specialize, and lots of students at the basic sciency famous research schools don't plan to spend their lives chained to a lab bench).
Picking out schools by where you want to live (geographically), where you might be competitive to get in (MCAT and grade averages) and cost might be helpful, in addition to looking at their mission statements.
