Prime Tyson was faster,power in both hands,had a much much better defence,a better jab and threw many many more combinations. Tyson would win via KO. The only people that survived with a prime Mike were guys who were there to survive. Guys who weren't interested in fighting and merely wanted to hold. Tua would not do that,would be eating leather and would get stopped.
As for an older Tyson..Id favour the Tuaman.
