Superman is generally considered much stronger than Batman in terms of raw physical power. Superman has superhuman strength that allows him to lift enormous weights, move planets, and punch with incredible force, while Batman is peak human but still within normal human physical limits.

However, the comparison isn't quite that simple:

**Superman's advantages:**
- Superhuman strength, speed, and durability
- Flight, heat vision, freeze breath
- Near-invulnerability

**Batman's advantages:**
- Superior tactical planning and preparation
- Extensive knowledge of Superman's weaknesses
- Advanced technology and resources
- Peak human conditioning and martial arts mastery

In DC Comics storylines, Batman has occasionally defeated Superman through careful preparation, kryptonite, and exploiting psychological factors - most famously in "The Dark Knight Returns." But these victories typically rely on specific circumstances rather than a straight physical confrontation.

So while Superman is overwhelmingly stronger in direct combat, Batman's strategic mind and preparation can potentially level the playing field in the right circumstances.
