Of course Warton, Top3 in 2007 ranking, my favorite. I dun realli think NYC will be a good choice to study/live becuz it is very expensive. 1500/mo for a basement in even some suburban aream as I heard from a friend there.
in IB, they may be similar. In PE/VC, I think Wharton is stronger since W/H/S are the three main schools for PE/VC. Or I would say, in top 10 schools, there are three tiers: Top 3, the rest of M7, and the rest of top 10.
