Goku vs Superman

I am honest. Random Estimation, but i assume Clark could still face and go Toe-to-Toe with C16 or fully powered imperfect Cell. So jeah, stronger than a "average SSJ1" who hasn't overcome the Limit of his Power, or Piccolo even when Piccolo fused with Kami in the Cyborg/Android-Saga.

But Cellgames-Level ? When the Fighters (Goku, Cell, SSJ2 Gohan, probably SSJ1 Gohan) could have blown up like the whole Solar System? If Clark would be that strong, he would have no Problem with beating down Darkseid. Like not at all.
