I don't know anything about Jefferson, but I will tell you about my experiences at Penn State.
First, Amber is the secretary for the admissions office and is quite possibly the nicest person on this planet. While that's trivial to its reputation, it is certainly something that I remembered. PS has its pros and cons. The facilities are nice, as they are attached to the Hershey hospital. This could also be considered one of it's flaws, though, depending on your perspective. Hershey, PA is pretty boring -- not nearly as exciting as Philadelphia. The clinical exposure at PS is fairly narrow (at least this was the impression that I got from my interviewer). He said that they deal with a lot of the same things over and over. Since it's a predominately middle class area in the middle of Pennsylvania there isn't a whole lot of diversity. This is why they encourage students to do a rotation somewhere outside of Hershey. Also, research is required, I believe. And PBL is used quite extensively. They have a wonderful simulation lab, too. The students that I met were nice and all seemed to be happy with their choice. I liked the school, but it definitely wasn't for me. Hope this helps.
