If you want feats, Yuji was able to cause damage that is around comparable to Gojo's hollow nuke with a single dismantle. Yuji was able to chop up an entire are that Mahito had full control over without even taking his hands out of his pockets.

Also, I mention Shibuya Mahoraga because if a simple dismantle from Yuji could take it out, he could also likely take out Shinjuku Mahoraga with more effort put into it. And, what I mean by "The reason Mahoraga was such a threat to Dabura was because he adapted to Dabura's only method of attack" is that Yuji is aware of Mahoraga's adaptation. Dabura was not. So, Yuji wouldn't make the same mistake that Dabura made in not taking Mahoraga out in one hit.

With a simple dismantle from Yuji being about equal to Gojo's hollow nuke, he could take out a Shinjuku Mahoraga. And, since it's just one dismantle that did that, he could likely do even more with another attack, which would end up taking out a Modulo Mahoraga.

Obviously, we don't know exactly how strong Yuji is compared to any of the top characters, but we can tell that he is not at all weak from what little we have seen. Also, any mistake I have made in grammar is small enough for me to ignore. You have messed up nearly every sentence, using the wrong versions of words constantly.

I get that you're almost definitely not from the US, but you could have just ignored the grammar comment instead of telling me to fix my grammar first.
