you're looking at 15 years of expanded content versus over 40 years. Star wars has had more time to become insanely overpowered. In universe instances of force ghosts collapsing stars to remake solar systems have happened. the force is broken, in any fight it wins. Based on "I can see the future and remake my own molecular structure to react to the future before it has happened" Death stars? Halo rings? The super weapons would not last long enough to be used, nor would the halo side CHOOSE to use the rings which would ensure the loss of everything BUT force ghosts, which ensures a star wars victory. Turbolasers have more power output and damage potential than the most powerful weapons the covie and UNSC forces have, and are barely below the forerunner tech. Proton torpedos match forerunner tech by the numbers. Star Wars shields are designed around stronger weaponry, thereby making fully two thirds of the Halo universe incapable of damaging the star wars universe. I have read the halo books, they're great. But there's star wars comics, games, movies, books, short stories (canon ones, not fan-fiction) and even board games and table-top RPG's that establish the force as this massively overpowered tool of near-godlike power. Not to mention the Yuuzhan Vong, a species that can create and control black holes of any size or strength, simply by growing plants.
