I love the sound of the BB Pros I have in my Les Paul, but for giggles and shits, I'm going to put in a set of 57 Classic / 57 Classic Plus. I know these pickups, and I love the warmth of the neck and the sting of the bridge. I'm going to keep the BB Pros though--may want to swap them out again some time.
I know boutique pups sound different, but I really like Gibson's pups. I like Fender's as well.
