Both steels rate very will on wear resistance. S30V is best at the working edge, but the refined edge is gone almost instantly. XHP is more similar to D2 in how it functions in that it can be both refined or toothy, because it uses chromium carbides which can be pretty easily refined (I think even AlOx abrades it). Between the two I would take XHP every day, but that is because S30V has done me wrong in the past.
