I really like what Gibson did with the new SG's.
As for PRS...
I'm not sure I'd make a Bigsby guitar my be all end all. They seem less stable than the PRS stop tail bridge. When it's set perfectly, the guitar will never sound out of tune.
With the McCarty type bridge, the guitar really sings. It's lightweight aluminum, and is coupled to the wood just perfectly. If Ted McCarty left us anything worth knowing, it's that his McCarty bridge is the best sounding bridge to attach to maple/mahogany. And interestingly enough, the Seth Lover sounds great in that design.
