I reckon it all depends on what sound you want and what kinda music you play. When I started playing seriously in the 60's I was playin' a lot of Dylan-ish songs and bought my D-18 new because a buddy told me they were great. Well, this particular guitar has served me well thru a musical journey of folks, country, blue grass and curently, prewar blues.

I also own other instruments but I like the bass that I can get out of the Martin. Nothin' like it fir bass and tone...

Of course, it isn't a mainstay in my blues playin' since I bought a decent playing reso off ebay...

But my vote: Martin.
