lol at people still trying to dismiss the world pressing feat and the feat of punching H'el so hard the whole earth was shaking. Seriously. It happened and it counts. Get over it and move on. What has happened that contradicts it? One low end feat in Superman/WonderWoman where it looks like he is struggling to lift a boat, which may or may not just be artist interpretation.
I also don't buy the argument about Supes's feats not having an effect on later fights. That is complete crap. How is Hyperion's feat of holding universe's together helping him in later fights? How is Thor's feat of planets busting and absorbing the god bomb in the Gor arc helping him in later fights? Why are Superman's feats the only ones that some people are applying this silly caveat to? Seriously people, be objective. I know that some of you don't like Supes. But please don't damage your own credibility with the hate.
Some other good feats that just happened are Supes scanning an entire area as he flies in and grabs Mongul in a thousandth of a second. Also, Supes stated in that same comic he could have killed Mongul in a single hit.
