A couple quick things:
A lot of what I'm seeing here is standard-fare strength debates.
We have a place for that!
And I know I'm late to the party, but with regard to the "STORY BY" on the
Super manga: it's a little bit of unfortunate credit translation vagueness by Viz. Toriyama's credit on the
Dragon Ball Super manga is the same credit he received on the
Dragon Ball Super television series, the same credit he received on
Dragon Ball GT, the same credit he received on the 2008 Jump Super Anime Tour special, and the same credit he received on
Episode of Bardock: it's 原作 (
gensaku), which means "original" or in this case "original work". It's saying he's the original creator of the franchise, and he receives that same credit on anything and everything produced with the Dragon Ball name on it.
(Yes, there is some obvious oversight and guidance that Toriyama provides to Toyotaro on the manga, as we've heard about in media interviews and have been explicitly told in the series' own interviews/bonuses.)
