I go to school in Boston and i entered thru a 6 year program, so i'll discuss pros cons.
NU pros:
Actually has a campus, more financial aid, better dorms/upperclass housing, less transfers, and if you're good enough can actually get a full ride thru pharmacy school. Co-op is awesome (ask some people around here whether they had to shadow an RPh/do work for free), and you actually get to pick where you want to work for 4 months at a time. Advisors actually do things.
NU cons:
Red tape, same classes with the same people in the same room for 3 years, classes are only offered at certain times so if you fail a class you have to wait a year to retake.
MCP pros:
Since it's a whole school dedicated to pharmacy (more or less), I feel it's a more professional enviroment, especially with the transfers. Not that this says much, but a lot of the upper level admins at my hospital are MCP alums, and pharmacy is a really small world.
MCP cons:
Bad professors/admin (but this changes frequently) , simulated pharmacy labs, bigger classes, school doesnt help with getting a part time job as an intern, etc
If it wasn't blatantly apparent, I go to NU. No interviews, and since there aren't as many transfers, a lot of the kids are boozeaholics with not that much professionalism. However, pharmacy school is what you make of it...
