Krupp steel for late Tigers. And rolled Homogenous steel for the rare early versions.

Wittmann rolled most lf his kills with the Early version but since Tybalt counts the Villers-bocage, its safe to assume that Wittman will get the late model.

(Not the Tiger II btw)

Krupp is 1.3 or 1.5 times better than standard rolled homogenous steel but deals more spalling which is a phenomenon where an armor shoots out shrapnels inside even if the shell that hit it did not pierce through.

The panzer III used rolled homogenous only.
