Well, before I visited both I had the clear feeling that Wayne was much better. After my visit they sort of evened out a bit, but it's hard for me to really say which I would choose. If you talk to the hiring partner at my (Detroit/Bloomfield Hills) firm, the top 20% at Wayne is welcome to come aboard, while the same is true for only the top 10% at MSU. I don't know if that is still true--I haven't really asked him about it since I got into Michigan.
If Dean Wu wasn't leaving, I would absolutely tell you to avoid Wayne. But he is leaving (thank God), and the new Dean has a good reputation, so hopefully the recent problems will be solved. Wayne is my undergrad, and I love the school, so I really wish them the best.
Facilities-wise, they are comparable. MSU has a fantastic mock-courtroom, and has a very nice distance-learning facility, and seems to have good clinics and a good trial advocacy program. Wayne also has excellent clinics, and the location is a big plus.
MSU is close to the capital, which is great, but the biglaw firms are all in Detroit, so the proximity gives the edge to Wayne on that count.
Honestly, it's hard to give a clear edge to either school. If you haven't yet, visit them both and see which one strikes a chord with you. If you are forced to meet Dean Wu, forgive Wayne for it, because he will be leaving soon. If you want any more specific information, feel free to PM me.
