Now before I go off, I like to say that I had never played Bungie's old game Marathon, so I'm not 100% sure of the lore, also I'm not sure who The Security Officer Is, so I'm going to vote Chief because he's the only one that I know.
So who would win?

Considering that that Security Officer essentially defeated chaos and entropy itself and in doing so basically became a god, I'll give him the nod...
