If such a table was created - that is, where BKP's were directly compared to other brands - you would have people thinking "well, why don't I just get a {insert compared brand here} instead?", and in most cases that would be a lot cheaper...
What I'm trying to say is, why would BKP cheapen themselves by putting their name next to another product (eg, duncan, dimarzio) which in my experience, simply aren't as good?
