The battle would be between Superman and Goku. Lavos would probably manage to destroy the others before Superman hurled him into the sun. After that, the bout would devolve into the Ultimate Showdown of Ultimate Destiny.
Some incarnations of Superman have had different levels of strength than others. In earlier incarnations, he would grunt under the weight of a small section of highway, whereas in some of the 70s and 80s comics he could stop planets in their orbits.
There's only one surefire way to ensure that your candidate wins a bout of raw strength; have your candidate be Bugs Bunny.
