Kakashi with Mangekyo in his left eye

Sasuke with Mangekyo

What if Kakashi got to Sasuke first at the Kage Summit? Who'd be left standing?

Personally, I think Sasuke would overpower Kakashi after a hard fight. But Kakashi does have versatility over Sasuke, as well as a lot more battle-experience.
