I know it's not really the point but I wish people wouldn't use shonen as a shorthand for high power stuff.

Shonen covers a huge range of stuff, even inside its own series. Naruto episode 4 is a drastically different beast to Naruto episode 444. Attack on Titan hardly exists in the same sentence as Dragonball. Dragonball and Dragonball Super are pretty far apart too, for that matter. Yu-Gi-Oh is shonen. Ao no Hako/Blue Box - a series tackling the deep question of 'Can a badminton player and a basketball player fall in love?' - is shonen (and also really good).
