Here's why I think the Gojo bait is not great writing and why you should maybe think so too (Spoilers till jjk 260).
We've spent the last few chapter consistently establishing a few things about our protagonist (Yuuji) and our antagonist(Sukuna).
1. Yuuji's father's soul is a reincarnation of Sukuna's twin: This instantly creates a connection between Sukuna and Yuuji.
As if you needed one outside of Sukuna's constant mockery of his former vessel's lack of "competance", and that most of yuuji's biggest losses can be attributed to Sukuna, building his wrath brick by brick. But surely adds to it all.
2. Yuuji feels incredibly lonely right now: Anyone he's created any sort of meaningful (?) Bond with outside of just 'hey you're an ally I can fight alongside with' is currently either dead or greatly incapacitated.
3. Also ofc the absolute damage that Yuuji has started incurring on sukuna. Damage that the slew of sorcerors before him couldn't. Forget about everyone teaching him abou love, Yuuji will show him Burning Rage.
This while also having hinted at Yuuji being possibly strong enough to do so on his own. He can go head to head with the King Of Curses with or without the help of his fellow sorcerors once he is able to harness this power.
Anything that was Gojo vs Sukuna feels absolutely irrelevant with the build up that Gege themself has been creating through the past few chapters.
Gojo's form right at the end of the chapter undercuts the pacing completely. Readers are more interested in those last 2 panels of Gojo which are completely removed from and rather jarring to the buildup between Yuuji and Sukuna. Fan interest in Gojo isn't their fault because that's what the chapter makes you focus on.
The only way I see this continue the buildup is if this is somehow Yuuji's doing or done with his knowledge, in which case it'd have been better to end the chapter by showing that Yuuji is aware of it and has an ace up his sleeve, bringing it back to the 2 relevent characters, and for people to stew in what Yuuji could be up to for a week.
But no matter what Gojo's visage there means, Yuuji in this moment has been so greatly undermined, not by his lack of strength, not by Sukuna outright demeaning him, but by the writing itself. By Gege.
And oh, how Yuuji deserves better.
