I am trying to get some opinions for non-professional home recording.
I just want to record 1 Martin acoustic guitar for mainly fingerstyle.

I would go with one or two SDCs. Peluso CEMC6 ($294) for a fingerpicked Martin acoustic (by far my first choice). Shure SM81 ($350) would be second. Either would be much better than the mic you listed. Stereo pair of these would be better, but might stretch your budget past $500.
If you want to use an LDC, try
AT4040 (see listeningsessions.com). I heard a shootout recently with an AKG Perception 200 that sounded very good on acoustic guitar.
