Powers and characteristics 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.
Mjolnir has the enchantment where only those who are worthy can wield it, such as Thor or Captain America. Hulk on the other hand, … while Stormbreaker can be wielded by anyone who has the strength to do so (though it can be summoned by those worthy of Mjolnir like Cap did). Case in point, Thanos.
In the end, Thor is able to coexist with both hammers, with Mjolnir being treated more as pet or a treasure, something he loves and handles with care that ties him to the events that made him into a great hero, while Stormbreaker becomes like a child, carrying the future as it is wielded not by him, but by someone he ...

Storm breaker is meant to be the strongest weapon of Asgard and could even summon bifrost, says Eitri. But there is no enchantment or spell on it like it was on Mjolnir. So one doesn't have to be worthy to weild it, just the strength to lift it. Clearly Thanos is capable of lifting it.
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 practically looks like a propeller, which might be one reason that fans expect Thor cannot fly without his hammer. However, it only helps him fly faster. Mjolnir is a magical weapon, enchanted by the greatest mages of Asgard.
Meanwhile, MCU Phase 4 saw Stormbreaker being wielded by Thor, Gorr the God Butcher, Love, and anyone else who was strong enough to actually lift and swing it. This is because of the respective origins of both legendary Asgardian weapons.
If Thor decides to use the power of lightning onboard the Asgardian refugee ship to fight the villain and his minions, he may accidentally damage the ship, or worse, even kill his own people. So, he chose to hold himself back, allowing some Asgardians to escape with Valkyrie (Tessa Thompson) and Korg (Taika Waititi).
With these events, it can be deduced that Stormbreaker is powerful enough to overcome six infinity stones and kill Thanos, something Mjolnir couldn't do. There are more common abilities for Thor that Stormbreaker possesses. Stormbreaker is able to not only focus, but enhance Thor's abilities.
Thor hypes up the weapon which eventually became Stormbreaker in Infinity War as the "Thanos-killing kind" of weapon. However, there is a clear weakness between Stormbreaker and Mjolnir.
Mjolnir, Thor's primary weapon, is the most easily recognized symbol of the thundering hero. Bestowed with a blessed enchantment, this hammer can only be picked up by those who have been proven worthy of its immense power.
Thor's hammer Mjolnir was defined by the fact that only the 'worthy' could lift it – so basically no-one except the god of thunder (and Vision, for some reason). But when it comes to the weapon's replacement, Stormbreaker – which Thor forges in Avengers: Infinity War – Groot is able to lift it too.
Thor had the element of surprise and a weapon capable of overpowering even the Infinity Gauntlet. Stormbreaker powered through the gauntlet's energy beam but left Thanos alive long enough to succeed, making his victory in Avengers: Infinity War all the more devastating.
Who would win in an MCU fight: Odin or Thanos? Without the Infinity Gauntlet, Thanos stands little chance against Prime Odin. Odin is stated to be able to shatter the Earth.
Gorr the God Butcher possesses enhanced strength, durability, and agility due to his alien physiology and absorption of divine energy. Stormbreaker, a powerful enchanted weapon forged by Eitri, allows beings of sufficient strength, like Gorr, to wield it.
Stormbreaker did not open the gate to eternity. It was manipulated to activate the bifrost , which was then used to open the gateway by directing the energy against the seal: The weapon may have displayed some levels of “feelings” against its owner, but Gorr has the powers of the Necrosword.
In the MCU, Stormbreaker was forged by Eitri at the behest of Thor, as a weapon to use against Thanos and his Infinity Gauntlet. In the comics, however, Stormbreaker was still made by Eitri, but pretty much everything else is different.
Unlike Mjølnir, however, the weapon is not enchanted to prevent those deemed "unworthy" from holding it, making anybody with sufficient strength capable of using the weapon.
After all, no weapon in existence should be able to stop the combined power of the Infinity Stones, no matter how powerful the wielder is. Turns out, Thanos was taken unawares. He had just incapacitated all the heroes who tried to stop him. And did not see Thor — or Stormbreaker — coming.
In a fascinating interview with Collider, Avengers: Infinity War screenwriters Christopher Markus and Stephen McFeely revealed that Thor's new hammer in the film, Stormbreaker, was able to cut through the power of Thanos' Infinity Gauntlet, making it one of the most powerful weapons in the universe.
