Hey Scott,
I've personally never heard a difference in tone between a cutaway and non-cutaway guitar, not that that would be an easy thing to test given there are innumerable nuances between two identical guitars. But if it help you any, I do recall Bob himself saying long ago that there is very little "going on" at that extreme end of the soundboard so if --
if-- any sonic even does exist between cutaway and regular, human ears would
not be able to perceive it.
Your 522 12-fret is a great guitar ...I love what Taylor does with the 12F models! Yours is not, however, a "CE" as that "C" denotes the cutaway, so yours is a 522e then, unless I'm missing something. BTW, if you even have a chance at demoing a 12F in a GA body, that is a sonic treat! Personally, I would love to have a 12F in a GA body, but those are rare to come by as I've played and seen exactly one out there in the wild.
With regard to the v-braced guits and their predecessor the x-braced, there is lots of polarization here. Some love what the v-braced brings, others prefer the tone --notably fuller low end, in general-- of the pre-V guitars. Which means there are the x-braced which was the default, then the AP-braced and the CV-braced on some of the Fall/Spring Limited models. So that can really confuse things as these LTDs varied wildly! But as for the V guitars, only
your ears can decide whether it's for you or not. Some call these more tonally balanced, others find them lacking. I can give you my opinion, but that doesn't really help you I think so your best bet is to audition them as you come across them.
