It's a good question I think, and one I really thought a lot about before sending in applications. I think Stanford, NYU, Berkeley are all good choices and it seems that Georgetown and Michigan place well with NGOs from the research I've done. Beating Harvard or Yale on placement might be hard, but at the same time I would not want to spend 3 years with a good chunk of those people (no one here on LSD of course, I'd love to go to school with you all!). If you are absolutely sure of your career plans, which it is hard to be, then I think it makes sense to look for the best school/money combo so that you graduate with the least debt without feeling like you sold yourself short. That's my plan at least, assuming I even have to make the choice.
I'd be happy with any of the schools where I applied, though I have to admit that Michigan is doing the best recruiting of the places where I've been accepted (as in they are doing some recruiting... the others aren't on the ball yet). But still hoping for Stanford and UNC actually (family and jobs for my partner attract us to NC)
