I have found certain manufacturers do have some flavor trends. I think the most apparent is Perdomo. Their construction is above average. I put it at the top with the others CNB mentioned. Most, if not all, of their cigars flavor profiles are grounded in "earthy" profiles.

That being said, a lot of their cigars don't develop, flavor-wise, past the earthy profile, or that profile overpowers the rest.

I think their newest line, the habano is a bit different from the others. I like the flavor, strong yet not as earthy, with some spice up front and the construction is far superior than a high 4 to low 5 priced cigar.
