snake, master cheif cant take on 5 metal gears in his life, time, and anyways snake would just use rex, attach wolf's rail gun to it and nuke master cheif, his armour and skilld cant save him from a nuke, and snake can just sneak up on him and snap his neck
well if you think about it look at snake now hes only 40 and hes got that virus and stuff.... id say if it was snake back in the day he would win but modern day mastercheif would win
