To me, it seems like you've narrowed the field to winners only.
Close your eyes and pick one, you can't go wrong with either of these fine acoustics.
Both are built to very high standards, both have excellent tone and will respond very well to setup.
Setup is the key factor in playability. I believe Martins are shipped with their bridges too high, so that the
buyer can tell the seller how he wants it and get it tweaked to exactitude. I've read threads on the
Martin forum by players who didn't know that. *shrugs But I've never bought a new one, so I dunno.
Both will likely outlive you and give good service for decades after the power goes out and all
the electric instruments and amps are mere artifacts of the golden age.
Now you just have to play a bunch of them, and buy the one that comes alive in your hands.
You can't order an acoustic without playing it first. Each one is unique and general statements
about their tone are not valid.
Anyway, what a cool quest to be on! You've slain the dragon, stormed the castle, and now there's a
princess up in each of two towers. Which one do you pursue?
