Doc Review? I'm sorry, but I don't think you know what you're talking about. BLS may not place all that well in biglaw in NYC but there are definitely other options. Just because they are "notorious" for inflating job stats does not mean that you will end up doing doc review.
I personally say go to the higher ranked of the two schools, but don't listen to people trash talking any T2 simply because they got into, and are probably not yet even attending a T1. I'm in the NY market and my understanding is that BLS is a well respected school in the area, if you can manage to not totally screw up while you are there you will be fine. As for big law top 10% is probably accurate. Just because there are several schools ahead of brooklyn in NY doesn't mean you can't get a job, after all NY is the biggest law market in the country.
