But seriously, employment oppurtunities are very similar, so unfortuantely there is no easy answer. It will probably be your feel of the school that will make one stand out. Although, depending on what you specifically want to do or what your interests are, there are differences in course, journal, and clinical offerings that may sway you. If you obsessively reseach the schools, like I did for hours upon hours, you'll find the minute distinctions that will help you differentiate the two and make a decision. But no point in stressing too much yet.
How do you distinguish between two schools so close to each other geographically and hierarchically? I honestly can't see how one is really better than the other. Visit both. Maybe you can visit with the faculty of both schools and pick the one whose faculty you can develop the greatest rapport with. I don't think there are major differences in any meaningful category between the two schools. It will probably come down to soft factors like the neighborhood of the campus, the general feel you get from the univeristy, the vibe you get from the faculty, ect. You can always enter them both in Cooley's ranking system and see which one they say is better...jk.
