Looks: to each his/her own. Personally, my priority list is sound, playability, reliability, and looks - in that order. The Buzzards do look pretty funky, but even the greatest bass players need a little extra noticibility onstage. ;-)
Sound: One of the reasons I got a Rogue is the bass and treble boosts. The bass boost rounds out the bottom end and helps push through the wall of guitar and drum sounds, and the treble boost adds growl and a lot of the tasty Alembic wood personality. At least one club member has upgraded his SC Sig with these boost switches, which probably makes for a great sound pallette. I found John's Buzzard sounds to be a bit sterile for my taste (the same holds for other graphite players like Michael Manring), so when forced to choose my upgrade from my 11 year-old Epic, I went for the Rogue. I hope to get a B2 at some point, knowing full well that its wood/graphite construction will probably sound less sterile than the all-graphite B1.
