Very close. But despite all flood, precursors and elite units of Halo, there is still Sith sorcery. And that's unimaginably powerful. It has been used to wipe all life- plants, insects, even the Force- the fabric of reality itself off the map. There's the thought bomb, which killed all beings in a large radius. Then there's the clones. Mass production. And the droids, too. Both are pre-programmed and battle ready. You can't infect a machine if you're a flood. Droids win out there. The Death Stars are powerful. MAC rounds aren't that big compared to it, and they are both well defended. The first one- fully built- was only taken down by the Force- which Spartans don't have. I call Star Wars as the victors, but it's close.
