I have to agree with L&E-pil; just received the package and I am impressed. I used to put Berkeley (still waiting a decision) over Michigan but now I am having second thoughts. I am still waiting to hear from Harvard, Berkeley and Columbia but Michigan's offer is very tempting!
I also used to put Berkeley over Michigan due to the reputation that the former has, but after receiving this package, which allowed me to understand the philosophy of Michigan Law School and the attention that the LL.M. students receive as constituents of a unique academic community, if I were to choose between the two of them I would definitely go for Michigan.
