well torah lishmah, I honestly am not sure about how good the limmudei chol are at chofetz chaim, but the bachurim are great, the derech halimmud is solid, the rebbeim are top-notch, and they really teach you how to learn and how to teach so you can go out in klal yisroel and make an impact.
Judging from your name, if Torah is your only concern, I would definitely go there. However, if college is also a consideration and a family value, maybe consider MTA as sam2 said. Or how about a hebrew academy in montreal, cleveland, new york, etc. Ner Yisroel lets bachurim go to college at night (apparently the R”Y said its okay a while back and thats the way it is).
