Hi, welcome to the forum.
With my limited knowledge, I think
the only difference between the two guitars that you're considering is Indian rosewood or Honduran mahohogany for the back and sides tonewoods, as opposed to an unspecified scource.
I have an A200ce and it is an absolutely superb guitar. I use it for flatpicking, fingerpicking and bottleneck slide and it suited to all these styles. I regularly de-tune using open tunings and normal A440 concert, with no effect on the stability of the guitar.
I have had no binding problems
; the luthiery and finish are excellent; it is simply a truly superb instrument!
