If you run 1H+S in PvE you are a tank. And for tanks defending, that gives extra resistance stats or decisive, that gives extra ultimate regeneration, are actually better than sharpened, because thanks are not expected to do damage. If you run 1H+S in PvP sharpened is definitely the way to go, because you actually need to do damage. As for the type of weapon, it really makes no difference, since 1H+S does not have a passive based on the type of weapon, as 2H and 2W have.
