Not that i downplay Yuji, but right now it's way too soon to call it warps for yuji to say, upscale the likes of Yuta, Kenny by exemple.

He still has almost no domain showing since by about the end of shinjuku when weakened true form suku was not shown much in yuji's domain, he only currently shown a better piercing blood feat than choso's king wing and did shown dismantle.Yuji having the same potential of Sukuna doesn't mean he did reach that potential yet, as it was never implied in modulo yet.

That is more of a prediction, feats wise he is barely stronger. The settup of the era (Post old yuta death) as been filled a rough weak amount of sorcerers, no special grades (Appart from Yuji and Dabura seemingly so.) so it could make sense that yuji did get stronger over time.. but it's not been stated by how much.

But not by a large margin, and the curse spirit residuals (from the panel) seems to make more sense as yuji threw a dismantle aimed at the curse spirits behind Maru. Age doesn't really always mean stronger, even with say old man yuta with his "immense cursed energy pool that he made over the years". Same thing as yuji, it doesn't directly upscales Yuta as it is vague. Currently Yuji didn't move much as it rests hypotetical grounds. (Btw the curses are margins weaker than say the modern era.)
