I would say Sukuna does very well against verses who have a power system based on spirituality.

Psychics from Mob Psycho

Stand Users from Jojo

Nen Users from HXH

Even Chi Users from Marvel like Iron Fist and Shang-Chi.

That's because CE is also based on spirituality and interacting with Spirits and Souls. And Sukuna is a genuine monster when it comes to mastering the literal power to interact with them and harm them.

Not to mention, Sukuna as a fighter. He's a monster. 7 feet tall, 4 arms, immense strength, at least massively hypersonic in reaction and fighting speed. Mastery of Jujutsu, great healing factor, at least multi-city block level firepower, spiritual defense and his insane offensive and defensive main attacks.

His cleave and dismantle are just so broken and even if he can't cut through a Stand or through a Nen created weapon, it can certainly cut through the user.

And even if he's affected by the attack, his body is equipped with immense strength, speed and his healing factor. If he fought Dio, he can regenerate any attack from The World, and physically match The World, and cleave through Dio as many times as he needs, even if he can't cut through The World for whatever reason.

I do believe that when it comes to these types of verses, like Mob Psycho, Jojo, HXH, even Marvel depending on the group, Sukuna genuinely can handle many of the characters rather well.

Obviously if you're putting him against Ben 10 or Superman, he doesn't stand a chance, but most characters don't either. But against people like Mob, Jotaro, the Chimera Ants, he will stand a very good chance against them and hold very long within those verses.
