Doomsday was merely koed by a Guardian committing suicide and Guardians have some of the most beastly showings for skyfathers. Heck at that time the GL CPB was just a portion of their own powers.
A minor psychic imprint by Krona had Hal seeing everything in cosmos and he could fix everything as well.
And did Superman KO prime under normal healthy circumstances ? All I remember when when they were both weakened, which suffice to say, skews things a bit.
Superman never went all out against Prime though. He was always trying to redeem him.
The destroyer on the other hand, has easily taken Mjolnir's best and to my knowledge only has one showing of breaking as mentioned before.
Jarnjborn recently cut it. Thor's hammer shot is fine and dandy but its not comparable to an all out punch from Superman that kills Doomsday.
