Hey, first off… congrats on getting accepted too both. Cost is always a major factor and I might normally say go with BSU, but Northeastern has probably one of the best co-op programs in the country. Its a lot more, but you walk out of graduation with a year of professional work experience. My wife went their and she swears by them. The campus is huge and right in Boston with lots of students commuting. Good luck with your decision.
BTW, when did you find out for NU? I applied myself and still waiting notification.
