Six was one of the best Spartans at the time of reaches fall. He was the best besides chief. And he went out like a pro. Killing so many elites, grunts, jackals, and who knows what kind of sh#t before being taken down by a whole gang bang of zealots (maybe the arbiter was there, but hey we don't know) Locke is...tricky. He wasn't a Spartan. He was oni. [spoiler]Nobody likes ONI[/spoiler] After the whole Halo ring Nightfall thing he was recruited and became a Spartan hit man. Then he became the main protagonist in halo 5 and did a awesome job at that. His armor also surpassed anything else. With trackers, scanners, thrusters, it'd leave noble 6 in the dust. But I'd have to say 6 wins because of one element. Customizable armor for campaign . [spoiler]OOOOOOOHHHHHHHHHHH GET REKT LOOCKE[/spoiler]
