The first fight between the four Supermen in Lex Luthor's gala, hands down.
First, there was Superboy and Eradicator. Despite Lex's clone getting a couple of hits in, the Kryptonian program quickly turned the fight into a Curb-Stomp Battle, by literally stomping the clone into the ground, and giving him a No-Holds-Barred Beatdown.
Next, there was Steel intercepting Eradicator's Coup de GrĂ¢ce to Superboy, gaining his attention. Steel even managed to knock the Eradicator around with his hammer. He even got a few impressive hits better than Superboy, up until the battle turned into yet another Curb-Stomp Battle in Eradicator's favour.
Finally, there was Cyborg Superman challenging Eradicator, and he was the one closest to beat the Kryptonian Living Weapon in a straight up fight. The battle itself culminates in a Brawler Lock, with the Cyborg charging his Eye Beams and the AI charging his Hand Blasts, which inevitably ends with an explosion which devastates the interiors of the building, and drained Eradicator of energy.
The Justice League's full roster taking on the Parademon invasion. The first invasion was a disaster the League barely averted; this is more like cleanup.
The fight between a recovering Superman and Cyborg Superman in the Watchtower.
A villainous CMOA for Henshaw. He thwarted Darkseid's plans by ripping off the cranial processor connecting his subconscious to him, and ripping off the Mother Box on his chest. Painful? Yes. Awesome? Hell yes.
Superman's Dynamic Entry by crashing the rocket he's riding right into Henshaw.
The entire first round of the fight was in Cyborg Superman's favour. Despite Superman getting a few good hits in, Henshaw showed him that the recovering Kryptonian was no match for him, even doing a Punch Catch. To put it simply, up until the solar shields were lowered, Henshaw was putting a Curb-Stomp Battle on Superman.
Lois helps to turn the tide in the fight against Hank Henshaw by lowering the solar shields in the Watchtower, giving Superman a power boost thanks to the sun's solar radiation, allowing Superman's strength to come back.
The fact that Superman didn't win the fight with his brawn, but his brains. How? By getting close to Henshaw and embedding the Data Matrix crystal to his forehead, allowing Eradicator to kill Henshaw's consciousness from within. Superman won't kill, but he knew Eradicator won't hesitate.
Henshaw: You won't kill me, and I won't stop until I kill you.
