In Apokalips now, the mother box effective cut Apok off from the rest of their reality, thus weakening DS from drawing power from the source. Where the Omega gets it's power. And Superman blitzed DS in the source wall after DS has literally pimp Smacked Superman and rejected a full charge from Superman. DS hit himself with his own OE after WW blocked it. Thus Superman got a sun amp against a weakened DS.
It doesn't matter how Superman defeated him, the only thing that matters is "he did it".
Another thing. Superman showing against Doomsday was far better than Darkseid. Darkseid got 4 shotted, Superman almost lasted an entire comic against Doomsday on more than one occasion, he was even weakened at one point and still held his own better than Darky.
