There's a battery options thread:

From the small bit of research I've done, most of the major brands buy their AGMs from the same manufacturers.
Long ago I posted pics from the websites of 3 major auto parts retailers, and from the fine details of the battery cases, you could tell they were all the same one, just with different labels.
Bottom line, the Autocraft is probably a fine battery, and likely will be from the same manufacturer as a comparable one from AutoZone, O'Reilly, Pep Boys, etc.
