I think I'll pick the Ivy in the end. Would love to hear your experience, if you have done any study in the UK, though.
Regarding the Ivys. I had a lot of respect for Yale, especially on the colonial track, but I've heard it's a disaster lately. I hope they recover. Particularly, I have no interest in Harvard. I heard that they are very culturalists and I don't share that vision. The same goes for Princeton, but I don't have many references from the department (I didn't even apply), so I can't comment. Brown seems like a pretty healthy place to go to grad school; I think that reason only would be enough to go. UPenn seems like a good place and actually something to consider but I have heard its faculty is mostly male. That discourages me, in general. I have heard that going to Columbia is too expensive (housing costs), and that it is one of the most stressful environments, but isn't grad school always stressful?
