There's plenty of room for competition, and it's what Jump wants and needs.
In 1998 we had JoJo, Kenshin, Hoshin Engi, Takeshi, One Piece, Hunter x Hunter, and Shaman King all running together. Plus other really popular series of other genres.
2004 we had One Piece, Hunter x Hunter, Shaman King, Naruto, Black Cat, Bleach, Buso Renkin, Reborn, D. Gray Man, and Muhyo and Roji.
The best periods of Jump are always ones with lots of battle manga competition.
Right now having just One Piece, My Hero Academia, Black Clover, and Kimetsu no Yaiba aren't really quite scratching that weekly battle competition itch.
I want Shiibashi and Utsumi to come back soon.
