Funny discussion here.

As much as I approve to the fact that a certain material can surpass others in certain ways, as seen with samurai's using paper as defense which worked as good as iron (or was it steel?), but seeing as mithril, adamantite and runite would already require a master smith to harness, the smithing and melting of such ore would be top notch.

As seen in the Lord of the Rings movie, the troll's spear doesn't penetrate the mithril in the slightest, and in the novel Betrayal at Falador, the adamantite sword slices through steel like butter which leads me to a pretty straightforward conclusion:

Adamantite and mithril is BY FAR superior to iron and steel.
