Short answer: Superman is far stronger in raw physical power. Batman can sometimes beat him in a fight, but only through preparation, gadgets, or exploiting weaknesses — not by out-muscling him.

Why:
- Raw strength/speed/powers: Superman has superstrength, invulnerability, flight, heat vision, super-speed, etc. Across most continuities he can lift far more than any human (city- or planet-scale feats in some stories) and is functionally invulnerable to ordinary attack.
- Batman’s advantages: genius-level intellect, master tactician and martial artist, top-tier technology, and willingness to use kryptonite, red‑sun tech, magic, or ambush tactics. He is the planner who designs contingencies for stronger foes.
- Story factors matter: who wins depends on the version of the characters, the writer, setting (e.g., red sun/kryptonite availability), prep time, and whether Superman holds back for ethical reasons.

Notable examples:
- Frank Miller’s The Dark Knight Returns: Batman defeats Superman using an armored suit, Kryptonite, and planning.
- Most mainstream comic showdowns: Superman dominates physically unless Batman is prepared (or plot requires otherwise).
- Movie example: Batman v Superman (2016): Batman nearly kills Superman using a Kryptonite spear; the fight’s outcome is driven by story and circumstances.

Bottom line: Superman > Batman in raw power. Batman can beat Superman in specific scenarios through preparation, resources, and exploitation of weaknesses. Want a hypothetical matchup (no prep, 1 hour prep, armored suit, etc.) to see how it plays out?
