The only thing I could add is that my experience "in the wild" is that the responses here, and the number of responses on one side or the other, mirror my experiences with the general population. Whether or not that reflects a greater echo chamber within the entire guitar playing population, I wouldn't speculate. But I can say as someone in the pickup business, these responses seem mainstream. Some people love their 57 Classics, many others think they are "just okay" or uninspiring sounding. Same goes for the Burstbuckers, though often people I talk to will say "the __ number is great, the other two are not so great" and the Burstbucker model that they think is the "good" one, is not the same as someone else who tells me the same thing. But that's no different than the Jazz, A2Pro, Pearly Gates, 59, etc. Players will have a favorite among those and find another one uninspiring.
