What's the point of bringing up who can beat who when we're not even at that point yet? Aside from that, Yuji just scaled a building at least 35 stories, with a jump, from the base level. It's pretty clear in 214 a change happened to him. And the fact he kept up with Maki - who we all know became a lot stronger recently - should further exemplify that. We don't really know anything about what he can do because we don't know how Kenjaku changed him.
I can't imagine who we switch to next week. Would've loved to know more about Tsumiki, but that's pretty much it for all Zenin clans relations.
Yuji is an experiment on manipulating the rules of Heavenly Restriction. The details will be fun but that's been literally his character from the moment Fushigoro saw him in highschool and remarked that he's similar to Maki.
I think something most people haven't considered with regards to Yuta is this:
his copy technique involves consumption of a part of the CT user's body. Whether or not he can counter Sukuna with his current arsenal of techniques is an interesting question, but
Yuta eats a piece of someone to gain their power. What's going to happen if another of Sukuna's fingers shows up? Will Yuta risk possession and eat it? Or maybe ingest a drop of blood from Yuji? Or a hair of Yuji's from his brush
when he was Sukuna's vessel?
Yuta
might be able to copy Sukuna's technique and with that, analyze it. He wouldn't stand up to Sukuna in terms of output, but he'll be able to copy him.
I really, really wish Gege would quit it with these throwaway characters who are supposed to have emotional impact with their deaths. You have to DEVELOP a character first to have any impact with their absence, either on the plot or emotions of the characters and readers.
