I this is based on my limited knowledge:
Morehouse: Small class size (56), generally produces primary care docs, located in ATL, less crime, lower cost of living, committment to underserved populations and community service, teaching hospital is shared with Emory students, I don't know about public trans here, slower paced (if you're from the North), patient population is mainly black and white (I'm speculating).
Temple: larger city (I think in the top 5 of the US), within minutes of UPenn, Drexel, and Jefferson medical schools (and law schools, etc), New contruction going on, more crime (higest number of murders in the US so far), level 1 trauma center for good clinical exposure (ditto on the camden crime/access), higher cost of living, but many options, many don't like the immediate living area of the Univ, but there are many options in nearby center city, or towards the subburbs 25 mins north on 611, public transprot not too bad, there's a subway system, and NJ transit to go to NJ and NYC ($25). VERY pricy for a "state-like" school, faster paced city (if you're from the South), patient population is all colors, white black, hispanic (there is a large population in and around Temple), african, indian, etc....it's more of a melting pot.
hope this helps!
