So thanos managed to stop the hammer... its been done by a many of people on a many occasions. To be honest though, Thanos is written so incosistantly that it's difficult to tell exactly where he's at in terms of power.
Post & Pre IG, there were times when he had a difficult times hanging with the Surfer and others on similar power levels. Then all of the sudden he was given boosts to his power with little or no explanation, and manages to take on near omnipotent beings like tyrant and odin.
The guys all over the place in terms of power, and it really depends on who's writting him as to where his power level is at. At the height of his power, I still think Thanos would have much difficulty taking on Thor and Superman at the same time. Thor and Superman are dangerous opponents when using their full power(ie look what happened to Mangog and Doomsday) There at the the top of the heap when it comes to superheroes, and generally are portrayed as characters who are able to overcome against all odds regardless of the situation.
Overcoming Superman alone would be a daunting task for Thanos to achieve, throw in the Thunder God, and the Mad Titan has really got a battle on his hands. IMO in a chance battle, Thanos would probably put up a good fight, but be defeated by these two more often than not.

Obviously Pre-Death power up Thanos didn't have a problem beating up Thor & Thing. And then when he died, Mistress Death gave him a power up so he could carry out her task of killing half the universe to balance life and death in the universe.
ejumacation its a greight thing. 😈
