Stormbreaker has the additional power to summon the Bifröst, allowing Thor to teleport anywhere in the Nine Realms. Screen Rant has identified Stormbreaker as the more powerful of the two, based on this ability, as well as it being a much larger and edged weapon.
Stormbreaker is one of the most powerful weapons in the MCU, displaying extraordinary power not yet seen while Thor wielded Mjolnir. Gorr was able to use the power of the ax/hammer to open a portal to Eternity.
the Destroyer. The very first time Mjolnir shattered, it was by one of the only beings actually capable of breaking it: the Destroyer. JOURNEY INTO MYSTERY (1952) #118 by Stan Lee, Jack Kirby, Vince Colletta, Stan Goldberg, and Artie Simek featured the debut of the enchanted armor called the Destroyer.
Overall, though, Stormbreaker seems to have the edge over Mjolnir once again. Strong enough to open the Bifrost, reach Eternity, and manipulate storms the same way Mjolnir can, Stormbreaker's powers are greater than that of the mythical hammer.

Originally Answered: Can Superman's heat vision melt the mjolnir? No. Mjolnir is made from a magic metal, futher enhanced with magic enchantment. Thor could throw Mjolnir through a White Dwarf Star, and it wouldn't even heat up.
If Thanos can lift Mjolnir, being an omnipotent being himself, with virtually unmatchable physical strength, he will probably be able to smash Mjolnir with his bare hands.
Odin's enchantment on Mjolnir in the beginning of Thor made it so only those worthy could wield its power. The most plausible explanation for Hela being able to hold and destroy Mjolnir is that Odin's death weakened the enchantment and she was too powerful for it.
Although Kratos never gets to wield the hammer, given his own extraordinary godly strength that slightly surpassed even that of Thor and even being able to hold Mjolnir back with his bare hands when Thor threw it at him, it's very likely that Kratos would be fully capable of using the hammer if he wanted to.
Colossus' ability to wield Mjolnir shows that he is pure of heart and ultimately good, despite recent actions calling into question his integrity. Colossus' heroic nature is evident in his willingness to sacrifice himself for others, as seen in the Legacy Virus storyline.
Gungnir is the more powerful weapon: In the MCU, Mjolnir is now known as a training weapon for Thor. Stormbreaker is more powerful than Mjolnir because it's a king's weapon while Mjolnir was never meant for a king. Gungnir, on the other hand, is a king's weapon, just like Stormbreaker.
Unlike the others, Zeus is not worthy to lift Mjolnir, but through a loophole, he can anyway. If Mjolnir is to enter his domain, Zeus's MCU powers should override Odin's enchantment, meaning he can hold Mjolnir.
While no one besides Thor has been able to truly wield the awesome might of Stormbreaker, Groot was the very first being to hold this weapon when one of his arms became the handle for the mighty axe.
Many viewers have pointed out that Thanos was able to lift Stormbreaker without a problem, but this is because the ax isn't enchanted as Mjolnir is. Others believe Thanos lifted Mjolnir (although briefly) and have even argued that he would be worthy of doing so.
It's important to note that the rules around worthiness had been temporarily suspended to allow this to happen. As soon as the fight was over, Superman couldn't lift the hammer anymore. However, under normal circumstances, without any weird interference, Superman is worthy of Mjolnir.
Loki is confirmed to be worthy of lifting Thor's hammer, Mjolnir, for the first time in official Marvel canon. In The Immortal Thor #5, Loki confidently catches and wields the hammer, showcasing his growth and heroism.
The simple answer is no. Yes, Hulk absolutely smashes Thor to the ground with Mjolnir, but, he's holding both Thor and the hammer. Hulk wouldn't have been able to lift Mjolnir by himself, but since the God of Thunder had a firm grip on it as well, he was able to use it as a weapon against his teammate.
After saving the world, making a play to sacrifice himself, and defeating Thanos' army, he was not able to lift Mjolnir in Age of Ultron. This shows that being a hero and doing occasional good deeds does not make you worthy. Tony wasn't a bad guy per se, but certainly not his best self yet.
While Superman could potentially overpower Thor, blows rendered by the mystical Mjolnir would likely impose serious damage on the Kryptonian hero. With his super-speed, the Man of Steel could probably avoid the Thunder God's lightning, but not necessarily, since Thor is just as fast.
During a Vudu Viewing Party for Avengers: Infinity War, co-directors Anthony and Joe Russo revealed a key difference between Thor's hammer Mjolnir and his new ax Stormbreaker: the latter doesn't require worthiness. That's why Groot was able to lift the ax, not because he was worthy but because he didn't need to be.
Mjolnir is not particularly heavy, it weighs 42.3 lbs. The fact that almost no one except Thor can lift the hammer has nothing to do with it's physical weight. The hammer is enchanted so that only those deemed 'worthy' are able to wield it.
