Depends on what you're doing. I have a K65ce that is a "Giggler" - Every time I play it, I just smile because it sounds so good. Big, juicy Koa tone that records wonderfully and looks that are drool worthy.
When playing live in a plugged in scenario, I honestly prefer my T5-12s1 (Maple top). Easier to move around with in tight situations, sounds great plugged in, and gives the added versatility of jumping from John Denver acoustic to Roger McGuinn Rickenbacker with a flick of a pickup switch and a twist of a tone knob. I guess that, technically, it's a GA body shape. I had a 654ce 30 Anniversary edition that played great and sounded okay, but didn't have the depth of tone acoustically that I was looking for, so it was sold once the K65 came into the home.
Finally, I can see how the GS would make for a killer 12 banger because they sound so good as a six string. Haven't played on yet, however, so I'll reserve official judgement until that opportunity arises...
