Please educate me on these super steels

Magnacut vs Z-wear vs k390 How do they compare?

I would usually go for magnacut on a folder for the stainless aspect, but since I’m choosing one of these steels for a fixed blade which I still will get wet during food prep and while using it in a snowy environment, I just can’t imagine I need the stainless aspect as much, because it’s easier to just wipe the blade after use (please correct me if I’m wrong).
