If we're including all eras, then Halo wins. No one in the SW Universe can ever match up to the power of the Forerunners. A mere mining ship is capable of destroying and building a planet, at least last I checked in Cryptum. The Mantle's Approach isn't even their biggest or best warship. The Fortress-class is a good example, being a 100km warship. Their ships are also made out of metal that can regenerate itself, pretty much as shown in some Halo 5 maps. Additionally, the ships can restructure themselves to maybe reinforce a damaged section, as shown in Halo 4.DaForerunner3 wrote:Absolutely no doubt. Star Wars would win. I've been the biggest Star Wars fan all my life, but I know enough abour Halo to understand it. Especially with Legends, Star Wars wins. Boba Fett in Legends in one of the most OP characters ever, and don't forget we have the Yuuzhan Vong. If it was the entirety of Star Wars vs Halo, Star Wars wins easily. Anakin, Revan, hundreds or thousands of clone troopers, all cloned from the most feared bounty hunter at the time. Jango Fett. Just saying, Halo is no match. Don't forget that Mandalorians' armor is made of beskar, a metal that can withstand direct lightsaber hits. Easy K/O for Star Wars.
The Yuuzhan Vong would probably be the Flood's favorite course, given literally everything is organic, including their ships.
Force users would be mostly unable to do anything against a skilled swordsman, especially a Spartan. The Force is useless since it can only affect things made within it's Galaxy. Spartans being fast and having lightning-fast reactions could outmatch a Force user.
Jango may have been feared and may have been the best, but not all Clones live up to such name because they're raised differently and taught different things, otherwise, they'd absolutely destroy the CoIS in every battle.
And not everyone has Beskar armor. If all you have to do to defeat a Stormtrooper is throw a rock at his head, then bullets or plasma would do that job wonderfully (and you can thank RotJ for that).
