My gut says Kelley, as it seems to be a much stronger program (everyone from there really impresses me) and has more learning opportunities. Bloomington, frankly, is also much nicer than South Bend.
Also, do you think Kelley would increase its offer (ever so modestly) to meet/exceed that of Notre Dame?
IMO, $$ should be the tie-breaker between two schools, not the primary consideration. It sounds like you like Kelley a lot more and you'll have better career opportunities out of there. It's not worth sacrificing long-term success for a little more $$ now. Best of luck!
