You should be forewarned that Newark can be a pretty dirty, depressing place to live. Even despite everything that Cory Booker is doing to revitalize the city.
Sure you're only a 20 minute PATH ride from the City. But you're still going to be spending the majority of your time in Newark in all likelihood.
Law school can be pretty depressing at times in and of itself. Studies show that the profession has high rates of depression, suicide, and substance abuse.
I think that a lot of people get so caught up in the USNWR rankings that they overlook quality of life considerations.
I just really hope that you take a tour of the city of Newark before making your decision.
