Great Value: $1.93
Comstock (Duncan Hines): $3.62
Texture and Appearance
The Comstock looked the best in both texture and color. The Great Value filling looked good, but the texture was not quite as good as the Comstock. The Kroger brand looked the worst by far.
The Kroger was by far the worst of the three. This was somewhat surprising because most Kroger products we've tasted in the past have been relatively good. The Comstock tasted a little better than the Great Value, but the two were really quite comparable. If you weren't comparing them in a back-to-back taste test, I doubt you'd notice whether you were eating one or the other.
Considering the price difference, in this case it is well worth it to buy the store brand. Just be certain to buy the Great Value filling.
