Nah he was easily comparable. His birth changed the trajectory of the world, present and future events.
Sukuna would have required more of his powerups to kill Gojo without Maho. That's why he needed Megumi, as insurance to beat Gojo easier.
I don't buy it.
If Gojo was comparable, he would have pushed Sukuna more.
The way it's portrayed, despite what the balloons say and what character state in the manga, it really looks like Sukuna won at the first opening he had.
Neutralised Gojo's strongest techniques and yadda yadda.
And he STILL had more power ups he didn't need to use.
It's like if this was One Piece and Luffy was fighting without G5, would you say he's being pushed?
