440C was one of the first super-stainless steels and many custom makers (including ABS) prefer to use it for their blades. Michael Black (Knives Illustrated) says that he has found some 440C blades that outperformed the newer purportedly better steels. It also depends on the blade profile and heat treat so you can't judge performance simply by the steel used.
