Depends.

Let's say you make two swords. Identical except that one is steel, the other mithril. We'll say that the steel one weighs five pounds(so we're talking longswords and the heaviest one handed swords) I believe that a lot of people overestimate just how light mithril is. I think it's about 1/2 the weight of the same volume of steel, so the mithril sword is about 2.5 pounds. Since it's far more resilient, that allows for a sharper edge, and needs WAY less maintenance, if any. Lighter sword types made of mithril would not cut well, however, you could obtain an obscenely quick thrust.
