Who would win Superman or T Rex?

Boringly enough, Superman. I wonder if it's occurred to anyone how pointless life would seem for Superman. It's not like his strength is impressive to him. Imagine if you found yourself on a world of people made out of tissue paper who could only jump an inch and move at the speed of a snail.

To them, you'd be "Superman", and you could kill all the tissue paper T-Rex's there you wanted to.

But would you be proud? Would it give you satisfaction?
