I interviewed at both places (and was waitlisted at MCPH, and accepted to CMS), so here's my take: I would take Hahnemann hands down (sorry Dra. Foxy) for several reasons.
1. Location - Philly vs. North Chicago to me is no contest.
2. Curriculum - CMS seems to not be particularly interested in using alternative teaching methods (PBL, etc).
3. Technology - The building at MCPH is very wired, and there appears to be good technology support. Outside of the computer rooms at CMS, I didn't see too much in that arena.
As far as I know, Hahnemann is perfectly fine financially (the bankruptcy is now ~5 years in the past), and the merge with Drexel is supposed to be virtually transparent to the students, other than a name change. It just allows the schools to combine financial aid, accounting, etc. depts.
