Lollar or Fralin HUMBUCKERS?

[ruger9]

Inspired by the "Lollars or Fralins" thread, which was about single-coils, I thought I'd ask opinions on Lollar vs. Fralin HUMBUCKERS. Not asking which is "better", just how they DIFFER from each other?

I've got a set of Lollar Imperials on the way for a PRS, just wondering if I end up wanting something warmer, or brighter, or whatever, how the Fralins would compare?

I realize there are umpteen pups out there that get rave reviews here... (WCR, Wolfetone, etc), feel free to chime in with ANY of the ones you've had if you've also had Imperials (or Fralins) & can compare.
