Unfortunately, I don't know tons about either school, but my thoughts:
UVA: really beautiful school, great interview day, a lot of interesting research going on there. Charlottesville seems like a great place to live. I was very impressed.
MCV: Don't know much, but I have a couple of friends there who are very happy with the school -- they've said that it's pretty noncompetitive, and they like studying one subject at a time. They also finish class at noon most days from what I've been told.
atdeben, what are your thoughts? I would really love to hear anyone's replies. 🙂
