Go to games at all of them, plus Drexel, that'll tell you which you like most. Since Villanova is out, the tickets for any of the other five schools will be really inexpensive.

You also don't have to choose one. There are plenty of people who root for all of the local schools, it's not like a Duke/Carolina thing. If anybody gets to the Sweet 16, the whole city gets on their bandwagon.
