Honestly I would say go with your gut. $100K is not that much to turn down if you feel that living in NYC and having the resources of Einstein would make for a better experience for the next four years. But also, if you don't really care and just want to go to school as cheap as possible, SLU is not a bad place to end up either. If I were in your shoes personally I would probably choose Einstein, but I can understand why you or someone else would choose otherwise.
