Go where you feel you will be the most comfortable/ successful. We both know the threads on BU are really not relevant anymore and I also got the vibe that BU is close-knit and has a family feel to it. I personally couldn't see myself studying in NYU which is why i never applied there until late November when I went into panic mode. The nice thing about the HPSP is there is no pressure to produce and you get to focus on learning dentistry with zero financial undertones unlike the corporate dentistry model most will have to resort to when they go to schools like NYU and Boston.
