Wake up after being forced to sleep on the couch for several hours, and I just got debates on Samurai 8, Ohba's sexism, and Jump+ for several pages.
Regarding the question of Kishimoto's editor, I'm almost certain that the series current editor, Taguchi, is basically just there as a figurehead. The lack of any mentioned contributions to the project (he doesn't even mention when he joined it) in his Manga+ interview is very telling.
As for the M+ question, I'm about the same as everyone else, Spy x Family, Jigokuraku, Summer Time Rendering, Blue Flag.
