I agree with the previous post. I am a current student at UVA and really could not be happier with my choice. As far as career options go, I do not believe you'll find much difference in the 3 schools, other than perhaps slight variations in the markets that are closest to each school.
If it's me, my choice b/w those schools comes down to what kind of lifestyle I want in law school, and what I want in my surroundings. Want to live and work in downtown Philly? Want to metro to class every day in DC, and be blocks away from the supreme court? Or, want to live in C'ville, a true college town that results in a pretty relaxed environment where almost no one here at the law school takes themselves too seriously.
Softball, Feb Club, weekly kegs at the law school, Libel Show, etc...even if none of these defining events of UVA law appeal to you, well, they at least indicate that EVERYONE takes time to do something they find fun....which means that very few people kill themselves for the sake of grades, which means you can do well and come out with a great job while having thoroughly enjoyed your law school experience.
Anyhow, that's my pitch...happy to answer further questions if you got 'em.
