Thanks all!
I dropped by a store today and fortunately, it both had a 12-fret and 14-fret GC in stock. Side by side, the 12-fret sounded fuller/better. However, the 14 fret was more comfortable for me. The shortness of the neck of the 12-fret oftentimes left my left wrist at a "weird" angle when playing basic chords. Must be because of my relatively long arms. (did anybody experience this?)
Although the 12-fret's sound was a dream, I think I'm more inclined to go 14-fret, due to ergonomic reasons. Again, thanks to those who gave advice on the 12-fret and I'm just sad it apparently did not work out for me.
