The Abraxas has the PAF-character for classic rock, just more output and more mids then Mules by example. I think this one does a lot of great tones, from blues to metal if neccessary. It would make the PRS very versatile.
The Diver sounds a bit more modern to my ears, but will do a lot of styles too. This one is really the metal-pu, though organic and beefy. It's one of the best BKP's for fluid solotones.
