Which is canon, anime or manga?

We should just Star Wars it.

Toriyama Canon - 1) The Plot he's written in the Dragonball manga, DBZ Movies 14, DBZ Movie 15, and any Super Plots he written. 2) all the characters he's ever created, no matter how they are used in the anime, movies, OVA, TV Specials or Videogames

Toei Canon - 1The filler written in Dragonball, Dragonball Z, the plots in Super not written by Toriyama, the plots of GT, OAVs, TV Specials and all other movies and the use of characters that Toriyama only penned and created, but never used in any plots he's written, and any characters that Toriyama never created

Media Canon - Anything, whether characters or plot that was never penned by Toriyama or Toei

I slice it like this, I know many people do it so I'm not original, but....-
Anime canon #1-db-dbz-dbgt

modern anime canon-kai-and super

manga canon-manga, jaco, and movies 14/15 and maybe super's manga...or the anime...its so unclear. all I know is I prefer the ball-Z-GT continuity

That would only be canon if Toriyama personally drew a new manga that implemented those ideas in it, but as it stands the sole purpose of Toriyama's draft is to serve as basis for a final product ( which is both the anime and the promo manga ) rather than something meant to be taken by its own. The same principle also applies to FnF's screenplay Toriyama personally wrote.

Looking at it objectively all of Toriyama's contributions to new Dragon Ball material are pretty much a bunch of unused ideas that never really made it into proper canon.

The main issue is that, especially considering some of the oddities we have seen in the Trunks arc so far, Toriyama isn't using the anime as a reference material for his later writing, which has resulted in some events in the new arc that resemble some old rough filler transitions, when new manga material contradicted previous anime-only material (like Gohan being set up to train post Super version of RoF, only for that to be completely forgotten now).

In fact, just for accessibility and speed, I think it's more likely Toriyama could end up using the manga as reference for his future writing at some point, although, of course, that hasn't happened yet.
