A few things I must address, if they haven't already been covered(started reading this from Page 1).
Bluewater, there's a serious flaw in your argument about Wonder Woman could've killed Superman at anytime. That him being handicapped thing? Do you realize that Diana pretty much only succeeded in slicing his throat with her tiara BECAUSE he wasn't really seeing what was going on? Why would he expect Doomsday to connect with a punch from that distance? In fact, that's why she did as well as she did during the fight aside from his irrational status, that he didn't really have the proper mind-set to fight who he was fighting. If he had known it was Wonder Woman the entire time, the most likely outcome when she threw the tiara was he'd simply dodge it. And it can only harm him if it can hit him. Which completely invalidates your argument that Superman couldn't stop her tiara with his breath under normal circumstances(which are what forum VS fights are unless extenuating circumstances are established by the OP).
And this, that Salsa showed earlier.
This is actually worse for your unsubstantiated belief that Diana is stronger than Superman than me pointing-out her failure to break his rape-choke. This isn't the best position for a leverage advantage either and he's calm. And in fact, I'd say it further supports that Superman didn't intend to kill Doomsday immediately(but wanted to make him "suffer" first) as this example of him showing such a strength advantage while calm proves if he was trying to immediately kill Doomsday, he would've snapped her neck and crushed her trachea as soon as he grabbed her by the throat when enraged.
And you show utter ignorance, or just hoping ignorance on others, when attempting to deflect that Diana blatantly states that Power Girl is AT LEAST as strong as she is by saying Karen's a Pre-CRISIS Kryptonian. Last I checked, she was, but Earth-2. Which were weaker than Earth-1 Kryptonians. Kal-L was specifically stated to be weaker than Pre-CRISIS Kal-El, and Superboy Prime seemed closer. Around INFINITE CRISIS, Post-CRISIS Kal-El and Kal-L fought to an essential stalemate, showing Earth-2 Kryptonians are roughly on par with New Earth Kryptonians.
Also, about you arguing that the Sun wasn't really behind her when Superman was about to punch her? Salsa pointed-out the Kryptonite glowing, but another thing one could point-out, is the fact that Superman's a bit in front and to the side of her, and the light is reflecting off him. Fact of the matter is, she's got the Sun behind her, is about to be punched into it, and for some reason ends up knocked to Earth, instead.
Also, you made the argument that Captain Marvel might be stronger than Superman because.....he stalemated Superman in arm wrestling until there was power-sharing? This makes no sense whatsoever. How is he stronger because he stalemated until his strength was decreased? And there's a serious problem with your argument besides this gaping flaw in logic. The arm wrestling match happened before Mongul Junior started training Superman, and thus Superman's power got boosted. In fact, this is how well Captain Marvel did against a weakened Superman. Prior to this, Superman had fought two large, powerful groups of metas, had some of his solar energy drained, and had unspecified but ever increasing exposure to Kryptonite before any of the fights. And Superman's particularly feeling it by the time he fights Captain Marvel. Yet, this is how Billy does.....

Despite starting off with a sneak-attack, the best Captain Marvel can get against a weakened Superman is a stalemate while looking inferior, including Superman blatantly showing superior strength by catching CM's punch.
This coupled with how Superman's looked better against Wonder Woman and the Ace androids(on numerous occasions) pretty much proves that Superman's actually stronger than Captain Marvel, despite the perception that they're equals.
Captain Marvel has also done better against Superman than Wonder Woman has, showing that he's stronger than her too, despite your beliefs.
When it came down to it on the DC boards, you didn't actually have any real evidence. Just an either manipulated or misinterpreted example, and the belief that Wonder Woman got stronger(even though you couldn't actually show any examples) and Superman got powered-down(despite you couldn't prove it, just showed you couldn't comprehend writers having different portrayals) and compared to the shared Earth moving example, despite Superman has numerous feats of strength that put that to shame, and the only examples for Wonder Woman that are better than that are shared with Superman.
Also, you never did admit you had no clue what you were talking about when you brought-up me giving the Brock Lesnar/Frank Mir analogy, and had Superman as Brock and Diana as Frank, and said you didn't understand how I could see that as being stronger. And showed Mir submitting Lesnar with a kneebar. And didn't admit you had no knowledge whatsoever of submissions or how they work. Here's some education.

While Mir used a kneebar, not an armbar, the principals are still the same.
