The "Reign of the Supermen" saga reaches its ultimate turning point in this issue where Steel and Superboy fight to defend Metropolis together with help from Luthor and Supergirl. Now that the Cyborg's true colors have shown they'll need all the help they can get, and at last at the end of this issue the real Superman has returned.
This issue ends with the first actual shot of the real Superman back from the dead. That makes it quite a landmark. And though the reign had a few chapters to go, this is where its final phase begins. 2 movies based on the death and return and neither has held the candle to the original story.
