Well, Yuta damaged Sukuna even outside the domain.
Also, Yuta and Rika might be amped, so how is that going to affect Yuji’s stats?
Maki clearly lacks statements and feats.
Gojo consistently praises Yuta and Hakari throughout the series as having the greatest potential. When Yuji became the vessel, Gojo started hyping him as well. Then you have Gojo mentioning that Todo will surpass Special Grade in one of the panels, even though Maki was also a Jujutsu High student at the time.
Gojo already has knowledge of Heavenly Restriction and has fought Toji, yet he never states anything about HR having exceptional or unmatched potential.
I think it’s consistent that Yuta, Hakari, and Yuji are portrayed as having higher potential than Maki and Toji.
Maki and CG Yuji were already relative.
Yuji had six Death Paintings and soul-swap training; the same goes for Yuta and Hakari.
Saying Shinjuku Yuta and Yuji are still relative to Maki doesn’t make sense. Not to mention, iirc, there was even a statement from Gege that Shinjuku Maki is on Toji’s level, and we don’t have any training statements or methods for Heavenly Restriction that would make her growth comparable to whatever the Potential characters like Yuta and Yuji went through.
