This is one of the most debated questions in comic book history! The answer depends heavily on the context and how you define "stronger." Here's a breakdown:

**Superman (Generally Considered Stronger):**

*   **Superhuman Physiology:** Superman possesses incredible physical capabilities:
    *   **Super Strength:** Superman can lift and move incredible weights, often depicted as being able to move planets or withstand the force of exploding stars.
    *   **Super Speed:** Superman can move at incredible speeds, often faster than the speed of light.
    *   **Invulnerability:** Superman's Kryptonian physiology makes him resistant to almost all forms of physical attack, including bullets, explosions, and extreme temperatures.
    *   **Flight:** Superman can fly, allowing him to traverse vast distances effortlessly.
    *   **Heat Vision:** Superman can project powerful beams of heat from his eyes.
    *   **Freeze Breath:** Superman can exhale a frigid breath, capable of freezing objects.
    *   **Super Breath:** Superman can create powerful gusts of wind from his lungs.
    *   **Longevity:** Superman can live for thousands of years.
*   **Power Source:** Superman's powers are derived from the absorption of yellow sunlight.

**Batman (More Strategic and Resourceful):**

*   **Human Limits:** Batman is a peak human being, meaning he trains his body and mind to the absolute limit.
    *   **Genius Intellect:** Batman is a master strategist, tactician, and detective. He is able to analyze situations, predict his opponents' moves, and find weaknesses.
    *   **Master of Martial Arts:** Batman is a highly skilled martial artist, trained in numerous fighting styles.
    *   **World's Greatest Detective:** Batman is excellent at using his detective skills, using evidence to solve cases and uncover secrets.
    *   **Advanced Technology:** Batman has access to an incredible array of gadgets and technologies, including specialized tools such as the Batsuit, Batarangs, and advanced vehicles.
*   **Weaknesses:** Batman has no inherent superpowers, so his advantages are skills.

**The Debate and How They Could Fight:**

*   **Direct Confrontation:** In a straight-up, no-prep slugfest, Superman would almost certainly win. His strength, speed, and invulnerability are far greater than Batman's.
*   **Prepared Battle:** This is where the debate gets interesting. Batman is at his best when he has time to plan, gather information, and create a strategy. He has multiple plans to defeat Superman, a lot of them are contingency plans in case Superman ever goes rogue.
*   **Kryptonite:** This is Superman's primary vulnerability. Batman has access to Kryptonite and has used it to hurt Superman on multiple occasions. He could use it to weaken or defeat the Kryptonian.
*   **Psychological Warfare:** Batman is a master manipulator and strategist. He could potentially exploit Superman's vulnerabilities by attacking his emotions and/or manipulating his surroundings.

**In summary:**

*   **Physically, Superman is vastly stronger.**
*   **With preparation and the right tools, Batman can be a threat to Superman and could potentially defeat him.**

The outcome of a fight between them is heavily dependent on the story being told, the rules of engagement, and the specific circumstances. It's often a source of drama and interesting storytelling, showcasing the contrast between raw power and tactical expertise.
