Is it fair to say Dabura is the weakest of the “strongest”, because despite his comparable/arguably superior power, theres a massive gap of knowledge and experience that he is unlikely to ever catch up?

Not downplaying Dabura power, his kit is insane, but i was thinking abt the gap in knowledge and experience that Earth sorcerers have

* Earth sorcery is baseline more advanced.
* Earth jujutsu society has a long unbroken history with the purpose of further perfecting sorcery. Yuji, Sukuna and Gojo can draw not only from their own intellect but also the knowledge of other sorcerers passed down and refined. FBE/HWB being one example of the kind of thing earth strongest just get to have by reading some books instead of having to invent them
* Gojo, Sukuna and Yuji spends most of their life fighting curses and other challenging opponents (multiple lifetime in Yuji case). Dabura was just kicking puppy until he came to earth so its safe to assume his home planet doesnt have a Toji or Void Generals equivalent, anything that can challenge him to the point that he needs to improve. His “i can figure shit out just by looking at it” feats are very impressive but Sukuna also does the same kinda thing, and Sukuna has seen alot more than Dabura

And by the end of the series, Dabura goes back to his home planet where he was kicking puppies unchallenged and will continue to do so, while Earth CE got ritual’ed so even if he goes back there wont be anything there either to challenge him outside of Yuji, and friendly sparring match is useful but wont be as conducive to growth as actual life or death fights.

So imo Dabura is the weakest of the strongest and will remain so, not because his power is weaker but because he lacks experience and knowledge, and won’t have many opportunities after EoS to attempt to close that gap
