Rochester >>> Emory >UIUC
Emory will say "But we just hired Patty/Penn" but they aren't there yet, they don't have a sequence designed. Rochester's placement speaks for itself.
I would go to Berkeley, the trioika of Pierson Hacker and Levy tops Harvard if you are set on a qualitative/historical approach.
Though if you are into welfare state politics (and aren't commited to a geographic focus) there is nobody better than Torben Iversen and Peter Hall at Harvard. Though, American, is relatively weak at Harvard.
In all honesty, you can't really go wrong with either so go wherever you think you would be happiest.
Visit weekends are BS. Most professors don't care about you or your research interests but are going to give you the hard sell regardless. Moreover, if a department puts on a great visit it DOESN'T mean its a great department. You have to really dig deep during your time at each place to find out if it is the right environment to spend the next 5-7 years.
I didn't and wound up at a place I am quite unhappy with.
