The acoustic maple series is pretty much on par with the acoustic electric maple series. Both have plastic bindings although the ivoroid on the acoustic series is a bit of an upgrade in my opinion. Both have an abalone rosette, and as Michael said, the major aesthetic difference would be in the fretboard inlays, which, again in my opinion, is not so major. The acoustic will feature a glossed rosewood headstock overlay, while the acoustic electric will have a bound (white plastic) glossed ebony headstock overlay. For my money, I'd go with the GA6, and I would go with an engelmann top to give it a bit more warmth and maturity. I might also consider the Expression system if you would ever have the desire to plug in. If you're a heavy strummer, stick with a sitka top (standard) or go with an Adirondack top. Have fun in your quest!
