Master Chief
Cause of his shields, sticky grenades, the ability to make speed, and the tanks and stuff, PLUS many great guns he's carries with him, also the energy sword can cuts throw deathstroke's sword
Master Chief. His armor is too much. Along with his arsenal and physicality. And Deathstroke's sword doesn't compare to Chief's. I will say Deathstroke is smarter and would probably get the first hit in. And he DOES have ways to kill Chief. Other than that, Chief outclasses him.
