Silver Surfer with the power cosmic, Molecule Man with power akin to the Beyonder, and Dr. Doom.
The problem with Superman today, right now, is the same problem he had before Crisis, and that is that writers give him the ability to have whatever power the plot calls for for him to save the day.

Today, of course the people he fights need to be incresingly more powerful, because Superman is back to having no limits to what he can do.
