If I were worried about corrosion I would go with 440C. If I wanted the best edge retention I would go with D2. If I needed something that I could sharpen easy then 5160 followed by 440C would be my choices. If I wanted something I could abuse then 5160 followed by 440C. In other words, it would depend on what I wanted to use the knife for. Generally, I think 440C is a better choice than 5160 as an all around steel and D2 is the best for edge retention.
