I just received the SOS bars, and had some Datrex on hand. I taste tested both of them with my family.

The Datrex bar is essentially half the size and nutrition of the SOS bar/serving.

The Datrex tastes like shortbread cookies, and everyone liked them.

The SOS bars have more coconut flavor, but were also good. Everyone enjoyed them as well.

Neither one is a gourmet meal, but pleasant enough even when you are not starving. In my opinion, they both tasted better than most energy or protein bars. The consistency and texture were more like cookies.

Both were a little oily on the outside of the plastic wrapping. I am not sure if this is from the inside or part of the packing strategy.

The Datrex bars reminded me of an old survival ration the military used to use, but with better taste.

My 2 cents.
