Both Pre-52 and New-52 Superman. Let's see his feats:
- Easily moves The Moon
- Reverses time with his speed
- Makes Lois forget her memory somehow
- If you count Superman Returns, he lifted an Island while stabbed with Kryptonite
- Took on 3 Kryptonians
Also, is Smallvile Superman stronger? Because he EFFORTLESSLY moved Apokolips???
