A key advantage that Hulk has over Saitama is his ability to heal/regenerate himself. Hulk has one of the strongest healing factors in all of Marvel, rivaling even Wolverine's ability to heal. This is not a power that Saitama is ever shown to have.
Zeno from Dragon Ball Super couldn't just defeat Saitama but could put an end to everyone in the One Punch Man universe. He is the god of the multiverse and is so strong that he can wipe out the entire universe with a single thought. If Saitama infuriates Zeno, he can kill him without even raising his hand.
Whether he has two hammers or not, Saitama will win against any incarnation of MCU Thor.

The more popular theory in the fandom suggests that, like Hulk, Saitama will be able to lift Mjolnir because of his brute strength, and not because he is worthy. In the One Punch Man universe, Saitama is by far the strongest being who surpassed his limit breaker a long time ago.
Saitama isn't built to conquer magic, chakras, energy, or even traveling through dimensions in an instant. This is where Doctor Strange has a solid advantage over him.
Saitama is incredibly powerful and he could decimate most Marvel characters if he saw fit, but Dr. Strange could trick him and gain victory through magical mental manipulation.
Like Kratos, Saitama possesses inhuman strength and endurance, but unlike the God of War, he has unparalleled speed and reflexes. If the two were to get into a melee fight, Saitama would annihilate Kratos because a single punch would likely destroy every bone and organ in the Spartan's body.
Apocalypse makes his way into this position on the list because he is technically stronger than the Hulk. He also has a multitude of other abilities, including telepathy, telekinesis, and shapeshifting. And that's just touching the surface of his powers.
World Breaker Hulk is stronger, more durable, faster, and has limitless stamina at his disposal, being able to fight seemingly forever.
8 The Incredible Hulk (2008)
Other than introducing the Hulk/Bruce Banner to audiences, the film has doesn't hold any significance to the overall MCU. Since the role went from Norton to Ruffalo, the character is basically reintroduced and reinvented four years later when Ruffalo took over.
A leading fan theory regarding the source of Saitama and most characters' strengths is that they trained and dedicated themselves to an inhuman level. The result of their high-level dedication is supernormal strength that is unusual for a human. In fact, many heroes in One-Punch Man can be linked to this theory.
Saitama (One Punch Man)
Saitama's strength and speed far outstrip even the Mad Titan's own, and these abilities would allow Saitama to easily overcome Thanos's regenerative abilities. The only question in this fight would be "how many times would Saitama have to punch Thanos to win?"
The Incredible Hulk is one of Marvel's most powerful heroes, but other strong characters like Thanos and Spider-Man have actually defeated him.
Being a supernatural deity, Rimuru is immune to any kind of physical attack, so Saitama's punches are a no-go. Moreover, destroying his physical body won't kill him unless his core is destroyed, that is, his soul. Until Saitama uses some special magic spell, he cannot defeat Rimuru.
Boros. Boros was the first on-screen opponent of Saitama that survived after getting punched, much to his surprise. In his fight with Saitama, Boros was hit with 3 normal punches, a Consecutive Normal Punches attack, as well as the shockwave from the hero's Serious Punch.
[ Still trying to do the math on how, the only thing to ever actually damage Saitama in the series is a cat scratching his face.
Saitama could defeat Deadpool with one punch, but then Deadpool would heal and come back to life. It's possible that Saitama could punch Deadpool so hard that his healing factor would follow to disappear, leaving the Merc with a Mouth as vulnerable as a fruit fly.
Thus, it is safe to say that Limit-breaker Saitama cannot beat Goku in his Ultra Instinct form. It is far too powerful a transformation to contend with. Even if Bald Cape lands his Zero Punch, Goku has been seen multiple times being more than capable of taking a hit.
Saitama may get full marks for putting up a good fight since he undoubtedly is stronger of the two. The problem lies with Saitama and Naruto's similar abilities: One-Punch and Rasenshuriken (wind release Jutsu), respectively. Naruto wins by virtue of his stamina and speed.
Can Saitama lift 200 quintillion? Gravity is about 1/5th as strong as Earth's on Io, so with a mass of 89.3 x 10^21 kg (half of Io canceling out the one-handedness), Saitama at the time could probably effortlessly lift 16 quintillion tons on Earth.
Saitama is the fictional testament that the phrase "absolute power, corrupts absolutely" isn't necessarily true as long as one stays down-to-earth. Saitama can literally destroy the world with one punch if he wanted to, but he doesn't because he only wants to be a hero and play video games like everyone else.
Third, Some people say Saitama has infinite power. That is not true as in the manga and the anime; it was said that Saitama has infinite potential, not infinite power, meaning he can grow infinitely strong as long as he trains.
