The thing to remember is these are 2 very different guitars.
If you like the PA taper neck the D-18 with Adi top is a great choice. It is a standard Martin with fwd shifted scalloped bracing.
The D-17M is a 15 series Martin with a spruce top instead of Mahogany. It has the A frame bracing. Not a bad thing, just different.
In the end, play both and pick the one that has the sound you want.
