Superman vs Steve

Captain America's powers come from the Super-Soldier Serum, granting him peak-human physical conditioning: enhanced strength, speed, stamina, agility, durability, and senses, along with an accelerated healing factor and longevity, all while remaining within human potential, not true superhuman levels like Hulk. He also possesses exceptional skills as a master tactician, combatant (especially with his Vibranium shield), and leader, making him a formidable hero. Superman (Kal-El/Clark Kent) possesses a vast array of Kryptonian powers derived from absorbing yellow solar radiation, along with high-level skills developed throughout his career as a reporter and hero. His abilities have evolved over decades, ranging from foundational strength to, in some continuities, reality-bending feats.
