It's really quite pointless to debate this kind of thing because it's practically impossible to truly "predict" the future in any reasonable way. Like, going into 2019, who would've expected that Kishimoto's much hyped and anticipated return would crash quite badly, that a middle-card battle manga like Kimetsu would suddenly become as popular as One Piece due to its anime, or that the biggest new series of the year would be a return from the author of Fire Punch in WSJ, and a Jump SQ author virtually no one knew about? Predicting Jump's long-term future is silly because there's no way one can anticipate the many variables that will come into play. All we can do is guess the immediate future based on the unestablished series running in the magazine, and which of the established roster seem close to ending. That's it.
Your mistake was thinking reddit is a reliable grading of anything.
