Godzilla generates radiation and Red Sun and/or Kryptonite radiation may be included in that. If so, Superman would inevitably lose. Godzillas mere presence would be death to him. But in terms of power, well the Superman Vs Goku Deathbattle demonstrated that all too well. What's more is unlike the Z Fighters, Superman has access to Star Labs and would make full use of Godzillas weaknesses, namely Cadmium. Godzillas body is essentially a giant nuclear reactor, Cadnium slows and can eventually halt nuclear reactions. It's the substance they use to keep nuclear power plants from going out of control. It was even used in a Cadnium laced super tranq to knock Godzilla out. Superman would exploit this once he figured out about the radiation problem.
