You'll find "better" brisket at Costco. They sell prime. Most of the local beef I buy is unrated and has nowhere near the marbling on their brisket. It tends to come out tougher and less flavorful, especially grass fed/finished brisket.

Eating the "shitty" meat occasionally is fine with me. I look at brisket as a treat to enjoy - and to share! I always give some to my friends and neighbors. 😄
