Superman struggled with an Imperiex Probe. One Probe was enough to trash the JL, with MM, Flash, WW, GL, CM etc. Probes were teambusters.
Later Steel had the Entropy Aegis and was able to hold back the conduits from WarWorld, which were powered by the power of Imperiex Prime. The Entropy Aegis was imprevious to Damage from Darkseids Omega Beams and was powerful enough to break through the combined power of the Quintessence (Ganthet, Shazam, Zeus etc.). So it seemed it was on the level of the Probes if not higher, as it was further optimized by Darkseid.
The increase in Power from Superman, who was able to oneshot those Probes had to be estimated and at least 10 times what it was before, at least or maybe 50 times more.
Anyway. Steel with the Entropy Aegis couldn't hold back a single conduit anymore because it's power increased "a hundred fold" stated on panel during OWAW. Superman while sundipped overpowered multiple of those tentacles, each one a hundredfold stronger then before, with utter ease while tanking all the damage Brainiacs defenses amped by Imperiex Primes power could throw at him.
So he was at least 100 above Steel in the Entropy Aegis and since it were at least two conduits one could argue 200 times. Steel in the Aegis was a threat to the Quintessence and I would argue 10 times above normal Superman.
And do we have a reference time-frame for the duration of such sundip?
