Re: PRS pups: Whats the deal?
I'm a big fan of PRS guitars. I own two...and I've swapped the pickups in both.
To be honest, I'd expect any high-end guitar company to have decent pickups. But I guess it doesn't always work out like that in the long run

. *cough*Gibson*cough*
I swapped the Dragon II's in my McCarty, as I didn't care for them one bit. They were just too compressed and undefined for my tastes...not terrible pickups by any means, but still not suited to my tastes. Out they went.
I swapped the #7's out of my Singlecut as well...though TBH I could have left 'em in there and still been happy with it. Those are actually very nice pickups...round the 8k range, very balanced, though for that axe I wanted something that was a bit more "in your face". So I swapped those out for a pair of full shreds.
I wouldn't call parker a better choice...apples and oranges really. I've never really liked the tone of a parker...maybe its the carbon glass fretboard, maybe its the thin bodies, but they just don't do it for me. They play very well though.
The california carved top models from carvin are probably comparable to the custom/standard 22 series from PRS. Though, carvins are rather notorious for their low resale value. A PRS keeps its value pretty well. Can't say much good about carvin pickups either
