If Iron Man stays ranged I could see him possibly taking it, yet to see his maximum damage amount. He normally goes close quarters though with opponents who aren't aerial call it plot but it's consistent.
The last time I saw this, Carter had to keep dancing around how he argued for people to not focus on versatility when it came to Hulk vs Superman/Thor/Silver Surfer/ect, only to keep arguing how much more versatile Iron Man was compared to Aquaman.

The last encounter between Namor and Ironman that I remember Namor almost killed him and would of if not for interference. Also that's an assumption not a fact, on top of that Namor and Aquaman's physiologies aren't completely the same.
Namor flies and to save a debate from Genis96 can't remember the name but Namor "possibly" also has less resistance to heat and heat based attacks then Aquaman
Ironman has an advantage in the fact he has range and flight but he generally for some reason doesn't use it to often when fighting grounded enemies which might be plot.
Depends if we're arguing a versus between Powersets or that of Characters.
