I'm so puzzled with Dr.Stone
For one part is by far the Jump manga of current roster with best promotion in West, even better than Hero Academia or Neverland in my opinion. You can read stuff from lots of people like Yonkou saying ''is the new pillar of Jump". When you ask someone in West about 3 Jump manga of current era, almost all of them will say for sure Hero Academia, Neverland, and Dr.Stone.
However, despite this and despite the ToCs, Dr.Stone is having poor sales in Japan, so poor that is the only title Shueisha hides the sales number because that would be like admitting the push didn't work. And yes, I still think Dr.Stone has been the Jump title with the most pushing in this decade.
Meanwhile Jujutsu Kaisen is the opposite case. It is having very good sales in Japan, but nobody in West cares about it (Yonkou for example treats Jujutsu like a thing that doesn't even exist).
Seems we are in a situation like Dr.Stone is really huge in West and minor in Japan, while Jujutsu is growing in Japan while not existing in West.
