You can't ask people to make an educated decision on who would win while ignoring everything that was shown about the monsters in the film. Final Wars Gigan was incredibly incompetent, while Monster X was incredibly powerful in both forms. Monster X's skin is armored and likely resistant to most of Gigan's attacks, while his gravity beams are of equal strength with Godzilla's atomic breath. The film shows that Monster X was more powerful than Gigan, so therefore Monster X would most likely beat Gigan.
