Nate Grey, Omega Cable vs Superman, Martian Manhunter.
The omega level brothers vs the supermen duo. Both mutants start the fight with shields up, already knowing they end terse a battle. This is Omega. Cable and Shaman Nate. Pre 52 versions of DC team.

I'd give a slight edge to DC, assuming J'onn could keep Superman's mind shielded. It wouldn't be easy, though, and I also don't think this is a 10/10 either way because of how many different ways the fight could play out.
Shaman Nate is somewhere among the top tier High Heralds, Cable (at his best) among the top tier Mid Heralds, based on showings. Pretty similar 'potential' power for both characters though.
Superman's useless when it comes down to Shaman Nate, existing as pure thought while still having access to your abilities is something Clark has no answer to. Nate's also a mutliversal telepath.
In the onslaught event, I remember Nate and Franklin Richàrds being rated as near equals. I also think both been stated to be equal to a Celestial IIRC.

Yeah, Nate's upper potential is clearly the highest. What exactly did he do to put him over the top on this fight, though? I'm not doubting it, necessarily, I just don't recall any specific feat that is an insta-win.
Can he, though? We're talking about one of the best telepaths in comics in J'onn. He doesn't need to be as powerful as Nate; just defend against him.
I agree with this at least, even though I might feel that they don't win.
That being said Superman didn't have any problems getting through Manchester Black's shields at the end of 'ending battle'. He doesn't have all the feats to match Nate, but the raw power of his TK shields should at least be around their tier.
I also don't see what prevents MM from simply getting through them.
If Superman chose to accelerate in under a second to beyond c he would first ,in achieving c, already destroy all of team one with gluonic plasma traveling at well to be honest ludicrous speed with no need for MM who would also likely be vaporized. Even forgetting this first model I have presented and "time manipulation" factored in with Nate (bs planck scale non sense pseudo science) who has with high meta reflexes at best Clark would in fact manipulate "time" in this battle before even Nate can sense or perceive whats happening. Never once in all Nates time and dimension hopping has it ever been displayed he perceived or moved through reality in the same way as Superman or Flash. Thanos was a nice flag that was planted to show Nate and Hulk in direct relation for people to draw their own conclusions.
