Star Wars. The powers of the Jedi and Sith can't be rivaled by anything in Halo. Think of Darth Maul for example. He can be pushed well beyond the limits of even an S-II. Plus, his skill with a lightsaber far overpowers an Elite's skill with an energy sword. He also has the ability to use the Force. I will admit that on a trooper battle, Halo still wins, with the Spartans, Flood, Forerunners, Covenant, etc, but the Jedi and Sith can easily overpower the Forerunner technology and the Precursors. And don't forget about the Death Star and Death Star II. Either could easily decimate any naval fleet a Halo faction could throw at them. There's no chance of a MAC round punching through a Star Destroyer's shields. To be honest, and I'm not trying to instigate a flame war, I think a lot (not all) of the people voting for Halo don't know much at all about Star Wars, and think that Master Chief and the Spartans can whip everything.
