Those are all very major research universities. Not one of them is known only for a single thing. For instance, four of Princeton's graduate programs are currently ranked #1 in the country (mathematics, economics, history, political science).
You might want to consider the "total package" of schools you're interested in. You may go to a particular school just because they have a high ranking program for your field of study, but you should also consider what type of students(as a whole) go to a particular school.
