You weren't clear when asking your question.
I can tell you a bit about BC. I don't know as much about the others but I got into BC, MGH, and NEU's traditional NP programs couple years ago. Your top priority should be to go to a school that 100% guarantees NP clinical placement. Some schools will mislead you to think that they place students, when in reality you have to do all of the begging to find preceptors.
First off, forget about Regis College - its NP portion is self taught and does not secure clinical placement. It's also not considered a reputable program in MA. Not worth it especially for Direct Entry.
PRO: BC is the quickest. Nursing administration and faculty are super organized. You'll find very few surprises. Professors are experienced NPs and most still practice. High caliber students across all programs. Clinical sites are 100% guaranteed! Finally, BC nursing is highly regarded in MA.
CON: 1) Some might think BC's program is too fast; 2) Because you'll take many NP classes with experienced RNs, you will face some criticism from fellow students or even preceptors, but generally people are friendly; 3) Classes are in-person (even for fluff courses), and some people don't like that; 4) There's a bit too many theory courses in the NP portion, but I think it's comparable to other schools?
Simmons has a decent rep in Boston and is bolstered by its proximity to top-tier hospitals. I've heard that students had trouble with NP clinical placement, but not sure if that's the case now.
When I interviewed NEU, I really liked it and was impressed. Consider that NEU might require that you work 1 year as an RN before going into the NP portion, and I think you might have to reapply? Keep that in mind.
UMass Worcester is probably the only school that is housed within a medical school/center. There might be advantages. I would ask whether they guarantee clinical placement.
MGH IHP honestly was unimpressive during my application process. (1) They royally messed up their open house presentation, wasted my time, and was unapologetic; (2) They were late in delivering acceptance letters and the letter was poorly written. All these reflects the culture of the program. I've also heard negative things about it being disorganized. Also, it's more expensive than other programs (at least for traditional NP). As soon as I got into one school I immediately eliminated MGH.
