I doubt that kind of “narrative intent” would be accepted as reasoning on here. Usually I’ve only seen feats/statements (and then outside material statements) be used as reasoning.
True, I this is vsbw, feats over statements. The thing i would give gong without much questoon is likely his level of
endurance. When he fought XXX initially, and got clawed, he took a burning wood or iron to cauterize the wound, which was metal as HELL, bro just walked it off, and kept smiling like it did nothing

. Even though I agree with bujin having the higher durability, Gongcheol's endurance seems to be higher imo, based off what I see at least.
Additionally, it’s also not always true (for other series and sometimes this one too). I wouldn’t say Team Bleach as a group is stronger than any of the Ex Reps (except maybe XXX), AM dowan in the training tower > XXX, and I’ve seen some takes (it’s actually a hot take of mine too) of Hoseong > XXX. Nothing personal against XXX.
Uhmm... I Don't think bleach was stated to be Ex rep level, rather, they were
just much higher than a 'normal representative'? Specifically when the band together through the power of... well...
friendship... (correct me if I'm wrong on that, but i doubt it).
Though I also have Gongcheol above Bujin because of the speed factor, feel like it’s hard to actually justify giving him 8-C durability unlike Bujin who actually has a multiple scenes of him taking hits from Sunjae-Synch Dowan.
The problem with sunjae dowan scaling is that we have no idea how much strength dowan used agaisnt Bujin in sunjae mode, what's worse is that dowan after running out of that mode could actually damage bujin and win. Also, I should be a bit more specifc though, dowan
could damage bujin, its just that bujin was just eating most of it until sunjae dowan wittled him down to dowans level...
Tid - Bit: Personally, I don't really see Bujin out-stattinng gong, like
maybe he has higher LS? But, I doubt he has higher AP than gong, and gong was more portrayed to be a endurance monster than bujin.
Shin actually has a statement from the system basically putting him above the ex reps. So he didn’t really need any “narrative” reasoning of being the last opponent anyway. Too bad he’s dead
Damn, looks like I forgot that one. But, it makes sense since the dude that much of a threat, and makes ji even worse, since ji offscreened Shin to oblivion lol. Srill, it's kind of crazy how much the ex reps got cliffed. In the latest chapter, we see dowan one tapping XXX with a random punch lol post GB
