i guess the fact that it has all high protein foods listed by category with their stats and provides protein amounts by chosen serving sizes. the other site you listed my have this along with the other features it provides, i am not sure.
i didn't list it as any comparison - just to throw it out there to whomever might want it or it might work for. so again - whatever it means to anyone.
and remember - sarcasm isn't always that bad. . . )
