You should get the Martin you fell in love with. You can get good blues sound out of a Sitka top. If you have the chance to try out both models in person, and you fall in love with the all hog-then get that one. [br][br]

I ended up with an acoustic I did not plan on getting (was going for a Martin 00-15) but fell in love with the Guild M20. It sounded right to my ears and felt good in the hands.

[br]I know this is not a definitive answer, but I do t think you can go wrong with either Martin. Blues has also been played on Sitka spruce top acoustics.
