I really don't know.
Most non-ISOM cigar makers blend so many different types of tobacco from so many different places, that it's dizzying.
I guess I love the Dominican Republic, since its home to some of my fav cigar makers, such as Arturo Fuente.
Second for me would be Honduras, since its home to Punch, Hoyo de Monterrey, and a lot of other full-bodied smokes.
Can't say I've had too many Nicaraguans. If I have, I didn't know it.
And of course, Cubans are always good.
