Fralins are really clear and bell-like. The high-output humbucker is a very nice, midrangey pickup that holds together pretty well with a lot of distortion and sounds pretty good clean. WCR's (my only experience is the Godwood pickup) are just freaking juicy sounding, full, thick pickups that sound alive.
I think they're both incredible pickups, neither one better than the other. It depends on what you're going to play with them and what guitar they're going in.
