Personally I would go for Bare Knuckle Pickups "The Mule" Basically a replica of the vintage PAF pickup, great tone. I only had a Pearl Gates once, in the neck position, but I remember liking it. This was around four years ago maybe. Personally I would not recommend the Gibson pickups. Bare Knuckle make some excellent pickups, but they're quite expensive.
EDIT: To break away from traditional stuff, Lindy Fralin P92s (split single coil P90 in a humbucker slot) sound incredible. Worth looking into Lindy Fralin as well, if you haven't already. It all depends what you're going for. I don't know what style you play, but those are some pickups I would look into.
