Here is some information about both fighters.
Being the son of Odin and the elder goddess Gaea, Thor is physically the strongest of the Asgardians. Thor is also capable of entering into a state known as the “Warrior’s Madness” which will temporarily increase his strength and stamina tenfold, although in this state he attacks friend and foe alike. Thor possesses a very high resistance to physical injury that approaches invulnerability. Thor also possesses keen senses that allows him to track objects traveling faster than light and hear cries from the other side of the planet. Thor has the ability to travel through time. His stamina allowed him to battle the entire Frost Giant army for nine months without any sustenance or rest; Thor has also shown the ability to regenerate wounded portions of his body, including entire limbs or organs, with the aid of magical forces like Mjolnir, Thor has superhuman speed, agility, and reflexes, enabling him to deflect bullets with his hammer. Like all Asgardians he has immunity to all Earthly diseases and some resistance to magic. Thor can summon the elements of the storm like lightning, rain, wind and snow. Thor is a superb hand-to-hand combatant, and also skilled in armed combat, excelling in the use of the war hammer, sword, axe and mace. Thor possesses two items which assist him in combat: the enchanted Belt of Strength, and his mystical hammer Mjolnir. The first item doubles Thor’s strength and endurance while the second is used to control his weather abilities; flight; energy projection and absorption.
For most of his existence, Superman’s famous arsenal of powers has included flight, super-strength, invulnerability to non-magical attacks, super-speed, vision powers (including x-ray, heat-emitting, telescopic, infra-red, and microscopic vision), super-hearing, and super-breath, which enables him to blow out air at freezing temperatures, as well as exert the propulsive force of high-speed winds. Superman currently possesses enough strength to hurl mountains, withstand nuclear blasts with ease, fly into the sun unharmed, and survive in the vacuum of outer space without oxygen.
