It's honestly a question of if you want to focus on a specific area of physics, and what kind of campus activities you'd prefer.

I went to NJIT for chemistry and got an education a little more skewed towards chemical engineering and business than what I would have gotten at Rutgers. I was also involved with some on-campus clubs but a bulk of my social life was spent with my friends who went to RU, William Paterson, and Montclair.
