Penn's is ridiculously expensive. IMO. And not worth it, at least in terms of NCLEX pass rates (they're usually in the low 90% range). It may help you get a job at Penn if you go to Penn, but I don't know.
I got accepted to FACT and start in May. Tuition is just about the same as Drexel, but the FACT students seem a teensy bit less frazzled than the ACE students.
Research 'em all and decide what's best for you. You may decide you like Drexel's program length (I think it's 11 months) or Jefferson's emphasis on getting you some MSN credits while you do your BSN, or Penn's Ivy League reputation.
Don't forget to check Villanova's BSN Express and LaSalle's program while you're at it.
Here are NCLEX pass rates through 2007, but it doesn't differentiate between ABSN and BSN programs at the same school:
