1. I gigged a GA7 for many years ...spectacular guitar, bar none, no excuses. And that old, tired mantra of "cedar is not for strumming" or "low headroom" is simply silly in my opinion and experience. The GA7 was my #1 go-to guit for many years until I sold it (another story, but not because of anything "lacking"). But bear in mind, depending on the year, a GA7 may have cedar, spruce, or a lutz top.
2. The GC, GA, GS, DN series of that era (mine was an 07 fwiw) had a slightly thinner top than their corresponding acoustic/electric models; in your case a 714ce. And this is per Taylor who I distinctly recall reading that the slightly thinner top of these "pure acoustic" models were to aid in resonance and dynamics, whereas the A/E versions had thicker tops as an eye toward stage use where said resonance can be a detriment. Whether truly the case in actuality, who knows, but it's their point not mine ...but I'll take it

3. Bottom line: if you're good with no cutaway, simpler aesthetics, and no electronics (though some had an "e" designation to denote ES equipped), the series is a spectacular one to consider. And they typically are priced lower than their numerical counterparts so they are a relative bargain, as well.
