Oda does not know how to write and needs to retire.
Let us take a very basic example of characters running up the stairs between the two and see how they are handled.
Here in HxH Gon, Killua, Shoot and the others are confronted by
Menthuthuyoupi a Royal Guard who is equivalent to a Yonko
Here you see Shoot's intense fear when confronted by the Royal Guard
while Gon doesn't hesitate at all
And here Shoot and the others reacting to Gon's resilience in not hesitating
So you see here, something so simple as running up the stairs became a very emotional scene with great character development of not just Gon but also the side characters like Shoot? No filler. No nonsense of fighting fodder for multiple chapters. Just straight up good story telling.
So compare this scene to Luffy running up the stairs fighting fodder for multiple chapters just so Oda can stale to reach chapter 1000 lmfao! The level of quality between the two are night and day. How can an author get away with admitting himself that he was staling to reach chapter 1000 is beyond my understanding.
I am not even asking Oda to be as good as Togashi. All I ask of him is just to do the most basic fundamental things like don't waste the reader's time on nonsense filler.
