The debate over who is stronger, Batman or Superman, is a classic one among comic book fans, and it really depends on how you define "stronger." 

Physically, Superman is far stronger than Batman. Superman possesses superhuman strength, speed, and a range of other powers like heat vision, flight, and invulnerability due to his Kryptonian physiology. In terms of raw physical power, Superman clearly outmatches Batman.

However, Batman's strength lies in his intelligence, resourcefulness, and strategic thinking. He has no superpowers, but he compensates with his skills in martial arts, detective work, and the use of advanced technology and gadgets. Batman has been known to exploit Superman's weaknesses, such as his vulnerability to Kryptonite, in order to level the playing field. 

In various comic storylines, Batman has managed to defeat Superman by outsmarting him or using advanced technology, but this typically requires specific preparation and circumstances. 

Ultimately, the question of who is stronger depends on the context of their encounter and what criteria you prioritize—physical power versus strategic and intellectual prowess.
