Yamauchi, and it's not even close. He was the only Nintendo boss who looked at the competition, took them head-on, and won. The rest has either side-stepped and won, or side-stepped and lost. Yamauchi was a gunslinger. He put the boss in boss.
Also, humor aside, he was the man who made Nintendo a household name. Without him, there is no Mario, Zelda, Metroid, Mario Kart, Iwata... there's nothing.
