puff was a behind-the-scenes guy at uptown. the public didnt know him. he also never wrote anything, nor made any beats.
bad boy had a bigger peak, but i wouldnt say they were a "WAY BIGGER DEAL".
Puff was a superstar in his own right though once he blew up.
Bad Boy was definitely a bigger deal. The credit you are giving to JD for crossing Mariah over into Hip Hop is more so Puff's doing as Puff produced the remix to "Fantsasy". He also did the "Honey" remix. "Breakdown" was Stevie J, one of Puff's Hitmen.
