Very tasty ... dramatic in presentation, but not really better than brisket in any significant way ...
I'm happy to have cooked some, and they are improved for having seen a bunch of smoke compared to the oven set, but top notch brisket is 1/2 the price of these at normal price, you lose less weight (bones vs not) ...
Now I know I'm not missing out on something particularly special when I'm having my favorite - prime/black brisket
