Depends on what you're looking for. The University of Michigan-Ann Arbor (where I go) has the largest program in the nation and a HUGE number of research opportunities. If you want the big school, big money approach, I'd highly recommend Michigan. However, some people like small schools better. I won't lie...the lectures here are huge. You can get a Bachelor's in psych here without ever getting to know a professor well. But if you're proactive, the opportunities here are endless.
