I think the "best" anything, particularly the "best" D.O. school, is very much a personal decision.
If you enjoy a particular area of academics that one school may be stonger in, then that school will look better to you.
If you like the geographical location of another school, then that's your place.
Decide what you want from your education.
Where you want to go to school. What areas the school is recognized for. Residency options. Tuition. Financial aid. And don't forget the all important fact about which school accepts you!
My suggestion...rather than asking which school is the "best"...ask people why they are attending a particular school. Or, ask why they decided NOT to attend a particular school.
Best of luck to you!
The best things in life are free, but you can give them to birds and bees, I want a 45....oh yeah...I want a 45.
