That isn't necessarily factual.
We simply don't know the difference in strength between Superman and Wonder Woman.
It's been said that he is the only being stronger and it has been said that they are equals.
Her durability is tied directly to her source of the strength: the Earth. She can take a punch just as well as Superman -- she just does not have the same resistance to sharp fast moving projectiles (such as a bullet). But, at the same time, she has no real weakness.
As far as overall power goes it isn't nearly as clean cut. She is an avatar of the truth -- a physical embodiment of a concept. Her power has been so great that she can caused reality to unravel. That is on a scale that exceeds Supermans physical might. Not to mention Diana has illusion casting, telepathic abilities, empathetic abilities, the ability to transcend dimensions, etc. She might lack EP but she has many other abilities that Kal lacks.
| > Gods in comics are NOT always more powerful than other super-beings. Heck, ALL of WW gift are of "godly" origin and she isn't stronger than Kal-El, she isn't thougher than him either and she isn't more powerful over all. In this instance the "Alien super-being" is greater on ALL account than the "Godly gifted" one. It's a FACT. Origin is just the flavor of the cake Not THE cake.|
