I'm in a similar situation, except I'm between Northwestern neuroscience and Columbia neuroscience.
Both have a number of faculty that I would be thrilled to work with (although Northwestern has the edge on that one due to the work of one person in particular). For me the choice is again higher ranking vs. (moderately) lower ranking, NYC vs. Chicago (I've lived in the northeast my whole life, I frequent NYC, and honestly on my couple of trips to Chicago I think I would prefer to live in Chicago over NYC), slightly more interesting faculty vs. slightly less. Northwestern has a better curriculum than Columbia (people at Columbia admit their coursework is weak), but again the question is simple: which place is going to give me the best chance to get the post-doc I want / the professorship I want
The professors I'm interested in are doing about the same caliber of work (similar number of journal publications in things like Nature, Science, J. Neuroscience, etc.). Rather tempted to just flip a coin lol.
good luck on your decision though (and sorry for not having any good input, just figured I'd commiserate with you lol)
p.s. which weekend were you at Northwestern? We probably overlapped
