It's not.
Not in my mind anyway, and I love both of them. I mean, they're both burley forward, Velvet being all burley, but it ends there IMO. From CB I get nutty burley and a "baking spice" flavor, with the occasional shadow of cherry... occasionally and rarely. It's an enigma for me, but like art, I know what I like.
Same with Velvet. It took a step towards the front of the class when Kentucky Club Mild/Blue was discontinued and I smoked the last of it. Man was that GOOD! I get no cherry at all from Velvet as some claim. I get no fruit, not even prune or raisin. I get a brown sugar/molasses sweetness, with the occasional shadow of anise and, believe it or not, coconut.
