I believe that Dante has alot of combat power over Goku, but sheer strength Goku would win. Its as simple as the fact that Dante has absorbed alot of different demons energy, but it seems to just make him a more diversified fighter with a small power boost, however, San-Goku builds the strength of his body, as well as learning new techniques, therefore I believe Dante would give him an epic battle, but Goku would eventually prevail.
