Who win a battle between two great light-heavyweight champions Archie Moore & Michael Spinks?

I'd say Spinks comes out boxing winning the early rounds, Spinks is to fast, but Moore catches him & puts him down about round 7. Spinks holds on to survive the round & comes back in round 10 to drops Moore with a right "The Jinx". Moore gets up & keeps pressing for the remained of the fight but is to far behind on the cards. Spinks wins UD.
