While Jump Force does view the verses within it as fiction, this just includes a non-canon version of their universes. So, in the game's story, Dragon Ball (for example) is treated like an individual universe (i.e. just a single Low 2-C space-time continuum) separate from the canon continuity. That and its High 2-A scaling chain isn't very good, since Prometheus is one of the strongest characters in the game.

But Dragon Ball Heroes, which isn't featured in Jump Force, should be much stronger through its waaaaaaaay longer scaling chain and better hax (The High 2-A ratings from that game also come from Beat's World, aka the Real World, viewing the DBH multiverse as fiction, funny enough, along with statements of Extra-Dimensional space created by Sealas and Demigra transcending space).

So tl;dr, Dragon Ball Heroes is separate from Jump Force and has characters way above baseline High 2-A + better hax.
