What is the best grocery-store brisket in Texas?

This weekend, I ate some fully-cooked brisket this weekend from HEB (pics to come). I'm curious to read what you feel is the best brisket for sale at a Texas grocery store. Not from a BBQ joint. Not from a caterer. Not from a stand-alone meat market. Rather, where's the best brisket from a general grocery store? And, to be clear, I'm talking about a packaged whole brisket, not brisket from the grocer's deli.
