If the costs are truly the same, as you said (and keep in mind that you should also take into account scholarship requirements IF they are the same due to a scholarship!), then you should focus primarily (actually, this should be one of your priorities regardless!) on western PA where you want to live.
Do you want to practice in western PA? Central/Southcentral PA? Northeastern PA? Philly? If you want central/eastern PA, I'd go with PSU if I were you. PSU will go up in the rankings slightly due to the money they're throwing around, while Pitt has faltered ever so slightly. It's networking is better in these areas.
However, Pitt is a great school for western PA, and Pittsburgh is a cheap city with decent things to do.
I hope this helps a little.
