In terms of raw physical power, durability, and speed, Superman is vastly stronger than Batman. He’s a Kryptonian with super strength, flight, heat vision, and near invulnerability; Batman is a peak (but still human) athlete.

Where it gets interesting is *prep time* and context:

- **Straight-up fight, no prep**: Superman wins almost every time.
- **Planned encounter, Batman has prep**: Batman often finds ways to level the field—Kryptonite, red sun radiation, power armor, exploiting Superman’s morality, etc. In many comics, that’s how he either stalemates or temporarily beats Superman.

So:
- Physically stronger: **Superman**, by a huge margin.
- More dangerous with planning, gadgets, and strategy against Superman specifically: **Batman can be**, in the right story.
