Between BC and Fordham, I would say its completely about location. If you want to work in Boston, choose BC; NYC, choose Fordham. If you are accepted into Georgetown, the decision is very obvious (GULC), but BU...well they will just make it more interesting because it really doesn't change the question that much. I suppose it also depends on what kind of law you want to go into, although I'm not sure if either of them have a particular streak that out shines the other.
In my own personal opinion, and I've been accepted to both, I would go to BC. It seems to carry a bit more prestige and it has a really good reputation for having a friendly environment. $$ might come into play to if you aren't heavily leaning towards one or the other.
