i've tried a couple too. i've always liked the more open-less "ipit" sound you get from the lower output buckers.
if i were to rank them from "more open-less ipit" to more middy (and modern-ish):
Skatterbrane alnico II - di ko alam yung output readings but it is pretty bell like sa clarity. got a set in the burny custom.
SD antiquity - pretty close to the skatterbranes (yung difference might actually be due to other factors like the guitars they were mounted on) and i'd say the best bang for the buck sa PAF clones (or any vintage style pickup for that matter). yung seth lover sounds almost identical but has a bit more clang and clarity.
Gibson burstbucker - di ko alam kung ano yung nasubukan ko (number 2 and 3 yata)
SD APII - warm and woody. tip: yung pang neck nito, actually sounds very good and PAF-ish sa bridge position (you can pair it up with a seth lover sa neck and it would balance nicely)
Burny late 80s-early90s VH1 - i've read that these got wound hotter after the first few years they were out. burny made these from '84 to '96. the older, early-80s sets would probably rank higher than this. the ones i sampled sounded a similar to a burny L8000 that was on a Burny LP custom i tried earlier this year.
Dimarzio Virtual PAF - ties with the SD'59 (from what i remember)
SD '59 - sound pretty aggressive when dirty pero for clean tones, these do actually sound a bit less ipit than the APII to my ears. got one on the Edwards' neck position, thinking about swapping out the JB in the bridge for a bridge position '59 too.
Gibson '57/'57+ - i sampled this set almost 10 years ago so my memory of them is foggy at best but i remember thinking they sounded a bit muffled (and this was back when i was into high gain sounds and liked high output buckers
)
