Let's see here....

Goku is already 2-B in a considerably weaker form of the one he's currently in; compared to Sonic being barely baseline 2-B. Same with Vegeta and Shadow. So, the heaviest hitters in Attack Potency are the Saiyans. As a plus, Reactive Evolution makes the AP gap bigger of which it is already.

Speed is equalized. That leaves hax, where the hedgehog's chances stand. Gravity Manipulation is useless, however Shadow's BFR and space-time manipulating capabilities actually give them the edge.

Overall, it comes down to whatever the saiyans oneshot the hedgehogs, or Sonic and Shadow use their hax. The former's more likely; I don't recall Shadow's BFR being used in-character that much—so my vote goes to Goku and Vegeta.
