Michigan is more highly regarded, but BU isn’t chopped liver – it’s also an excellent school with plenty of rep.
Since the money comes out about the same, I suggest that you choose based on fit. So compare the two on questions like these:
- Boston vs. Ann Arbor
- Vibes at both schools
- Food at both
- People at both
- Living situations
- Party scene
- Sports scene
- Weather
etc.
