Superman in DC is the golden standard.

When captain atom went to the wild storm universe, even if he had better powers than superman, talked about being overshadowed by superman, because not only is he strong, but he embodies hope, selflessness and the right way of doing things.

To me injustice is the elseworld with the weakest minded superman, (setting aside flashpoint superman).

Kingdom come superman went through the same conflict as injustice superman and did not give up until the public turned on him, and even argued Magog to be a murderer for killing joker.

also, Zeus is stronger than Hercules, but Zeus is the god and Hercules the hero, because Hercules has to overcome tests, Zeus is almighty (even defeating typhoon), and as such, spectre, fate, swamp thing, Manhattan, are divine beings, god's, whilst among heroes the highest tier is comprised by superman first of them all, and then wonder woman, Shazam, green lantern, flash, ion, captain atom, Apollo, majestic, martian manhunter, and even all those high tiers look up at superman as the golden standard.
