Yale > Harvard > Stanford
I, too, have no good reason for this, other than Yale just sounds like it would be the best...and from the little professor gossip I've heard, Yale wins out.
Chicago > Columbia > NYU
Chicago seems like it's got an amazing reputation and it's clerkship placement is fantastic. Obama taught there, too. The rest I have no real compelling basis for.
Michigan > Penn > Boalt > UVA
Michigan rocks (I'm biased). The rest is mostly personal preference.
NW > Duke > Cornell > GT
Meh. I love Chicago and think NW is underrated. Duke has a fantastic environment, from what I've heard. I know next to nothing about Cornell, and GULC is very, very large.
