That's what you get when it comes to debating fictional characters based on fictional characters that are based on mythological characters.
There will be a lot of ...slippage.
Suffice it to say that Superman is the strongest of them all (his strength levels can apparently expand to fit the situation), while the strength of CM and WW are below his.
However, for all intents and purposes the respective strengths are not discernible. It is a bit like trying to match the speed of the Flash vs Superman vs Black Adam.
There is a clear hierachy, but for all intents and purposes there is no difference (unless you are trying to beat instantaneous travel, in which case the Flash would win). For most observers they would all seem to be the same speed.
Same thing in strength when you look at Kal, Diana and Billy's alter ego. There is a hierachy (with Kal being tops), but there is no real discernible difference unless a very high level of feat is called for.
The best way of looking at it is the feat in whch Superman, WonderWoman and the Martian Manhunter pulled the Earth .....obviously all 3 were probably not pulling the same load, but what it showed is that all 3 were extremely powerful. Even though the weight dispersal may not have been 33.3% for each, even a dispersal of (my own figures) of 50%, 30% and 20% would still have the person pulling 20% being VERY powerful all the same.
Thus, all one can say for sure is that Superman is stronger than CM and WW, particularly when he stops holding back and decides to give it his all.
Apart from that the rest is just a waste of time.
