Simply to put it: No proof Superman is stronger. If one say Hulk stronger to Thor i'll agree because of his potential unlimited strength but Superman-Thor, no proof. Superman greatest feat, moving war-world(pluto size planet but with the help of a device.) Thor? I have already stated.
Magic renders Superman vulnerable. Remember Captain Marvel knocking him out in JLA (Grant Morrison run)? Or even in *gasp* Kingdom Come, the lightning bringing him to his knees? Well now, what more can lil' ol' Mjolnir do that would neutralize ol' Supey Supes?
Nullifying vortex (Mjolnir)
Thor is able to use Mjolnir to create a vortex around himself and others, if desired. This vortex has been shown take on many properties. It has acted as an anti-magic shield against the Juggernaut, disconnecting his link to the Gem of Cyttorak. It has been used to absorb the Power Cosmic against the Firelord. The vortex can be used as a virtually unbreachable wall, which was useful against an enraged Hulk while Thor wanted to consult with Odin. A vortex has also been created to stop the passage of time within the vortex relative to the world outside. This allowed Thor to finish a battle against the Cobra and Mr. Hyde while delaying death in the mortally wounded Jane Foster.
Detect energy sources (Mjolnir)
Thor can use Mjolnir to find sources of energy or magic. This has been used to find track down, among others, Magneto and the magic Norn Stones.
Absorb and redirect energy (Mjolnir)
Mjolnir is able to absorb and redirect tremendous amounts of various forms of energy. When redirecting energy, Thor has shown the ability to exert some control over it. Some noteworthy examples of absorption include absorbing Magneto's force field, rendering his vulnerable to physical attacks. Mjolnir has also shown the ability to attract and absorb Power Cosmic blasts from the Silver Surfer, removing a significant attack from his arsenal. Another example involved drawing the magnetic energy from a planet and redirecting it into a attack against a Celestial. Only the last example took any additional time or concentration to perform.
Godly essence blast (Mjolnir)
For those really tough villains, Thor is able to channel his godly essence through Mjolnir for a truly monumental attack. This has been used very rarely, as it can weaken Thor considerably. He has used this to kill Jormungand, the Midgard Serpent, to actually drive back the "unstoppable" Juggernaut, and to actually pierce the armor of a Celestial.
Interdimensional travel (Mjolnir)
Traveling to different dimensions (including Asgard) is possible through the use of Mjolnir. This can take three forms: Thor can transport himself and those near him to a desired destination, Thor can throw Mjolnir around a target and warp it to the desired location, or Thor can open a dimensional portal through which anyone can travel through (usually a surprised, onrushing enemy).
Mystic energy blast (Mjolnir)
Thor is able to project powerful mystic energy blasts from his hammer. This tactic is typically only used against opponents that also use energy-based attacks. Similarly, Thor can fire lightning bolts directly from Mjolnir. When this is done, the power of the lightning is magnified greatly.
Flight (Mjolnir)
Thor can fly using Mjolnir. This is typically accomplished by throwing Mjolnir and holding onto its strap. Once airborne, however, Thor is able to maneuver and change direction. This travel can be done at an incredible velocity; Thor has been shown overtaking spaceships that were travelling at near light-speed. After throwing Mjolnir, Thor can remain airborne until the hammer returns to his hand. There is obviously a lot more control here than Thor just hanging on for the ride, but it has never really been explored beyond this.
Control over weather (Mjolnir)
Thor is the god of thunder and storms and has complete control over all forms of weather. He can create raging electrical storms complete with thunder, lightning, hurricane-force winds, tornadoes and torrential rains. He can also create any of these phenomena individually. Another aspect of this power allows him to stop any of these weather conditions as well. The powers are shown as being channeled through Mjolnir. Also, Thor cannot be injured by lightning or any other weather-related effects.
To illustrate the extent of this control, Thor's power of weather can be compared to Storm's, a mutant imbued with weather controlling powers. Although very powerful, Storm can only manipulate existing weather conditions to achieve the desired effect. Creating a thunderstorm in a desert would take much longer than normal. Thor, on the other hand, creates weather conditions as a result of his godhood. Creating a thunderstorm in a desert requires no more effort than normal. While Storm can manipulate weather, Thor can just as easily undo her manipulations with little effort. In Marvel vs. DC, Thor defeated Captain Marvel by simply withholding the lightning that allowed him to transform from Billy Batson into the superhero.
Mjolnir as weapon
As a battle weapon alone, Mjolnir is a formidable force. Forged from the indestructible element uru, the hammer has two enchantments that are particularly useful. The first causes Mjolnir to always return to Thor's hand after being thrown. Or corollary to this is that Thor can "call" the hammer to him. The second is the famous "worthiness" enchantment, which prevents anyone but Thor from wielding the hammer. Of course, the vague wording of this enchantment has allowed a few others to lift the hammer is specific situations. The hammer has other powers which will be listed separately.
Is that enough? No...? I posted a comment from an e-mail by Jeph Loeb regarding Superman vs. Thor (older posters will remember me doing this). Will see if I can dig it up and show you all what he said.
Supes push the planet with his own power with light speed going agianst him and lift small moons he is stronger than or equal to Thors strength. And Supes get series, Thor whould never be able to even touch him.
A pluto planet size still. Nothing much. Supes is strong but not stronger. But true Supes is faster but Thor have high level of experience with speedters.
Thor losing to the Hulk? Even Hulk never admitted victory against Thor like he does when he fights others. Thor can take lots of beating from heavy weights and dishes out heavy stuff to them, even when restraining. When he unleashes he dominates.

Maybe that’s why humans drink the darkness that is coffee.
Let's end this debate once and for all. Thor and Superman neutral battlefield. Thor full potential and Superman not holding back. No interferences from the outside world what's so ever.
People with true comic knowledge please express people without don't even bother.
Woooh This is an original Thread, I wish it had been done before
Sorry Dude it had to be said. Atleast you get from me, someone who can barely spell whit, let alone use it. I know you want to 'settle it once and for all,' but surely this can be done on one of the other million Thor vs Superman threads.
