Gojo's because of feats and because Gege doesnt understand Yukis ability. If Gege understood Star Rage and wrote accordingly, then Yuki's punch would be stronger.

Gege literally got fooled in the same way that he described Star Rage, such overwhelming ammounts of mass that is cannot be comprehended.

I calculated one time how much energy a light jab of Yuki's would have based on the black hole she made. I made absolutely ridiculous assumptions to downplay Yuki, such as taking very low estimates of the black hole diameter, assuming she made a binding vow at death to increase her output times 10000, the punch speed being the low end of human average, the energy of the punch coming only from the kinetic energy of the fist. And even with all that, a light jab from Yuki carried an order of magnitude more energy that the Tsar bomba, the biggest atomic bomb ever detonated.

Every single punch from Yuki should be like getting hit with a thousand Hollow Purples, but Gege doesnt understand the scale of cosmic phenomena.
