Kevin Nash or the Big Show?

Kevin Nash and the Giant aka the Big Show go back along way back to the days of WCW in the New World Order. They were the big men not just of the nWo but during the Monday night wars era over in WCW. But the two would eventully face-off against each other in a one-on-one match. After one match the two had in WCW then-WCW president J.J. Dillion had to ban the use of the powerbomb move for a short while. But life after WCW to the WWE the two are older, wiser than before and are seen as to veterens who have paid their dues in the business. But in your own opinion who would you pick as the better big man to have the better wrestling career, Kevin Nash aka Diesel or the Big Show aka the Giant?
