Star Wars, technological advantage? Lol. Metaphysical advantage with the force, sure. Technological? Forerunners alone outpace anything in the Star wars universe. Throw in the Precursors and they're done. Hell, neural physics was metaphysical too, and probably equal to the force. Halo 1-3? Not a chance. But halo with all the books and the precursor's power? Nice try. Halo wins. Not to mention the Halos themselves. Fire in 15 minutes to kill a whole galaxy.
