User blog comment:Cfp3157/inFAMOUS vs. All! Premiere: Kessler vs. The Didact/@comment-422690-20140331004817

Personally, I think Kessler gets this one. Both have a great deal of experience using their powers, but the way Kessler's (and all prime conduits) manifest leads to them growing more and more powerful over time, to the point where he can somehow manipulate electricity to gain time travel powers. No, I'm not sure how the two relate, either.

Didact is incredibly powerful, but so is Kessler. Where the battle is really decided, however, is in the backup.

Didact gets forerunner troops, which aren't exactly a bad choice. Kessler, however, gets Conduits as well as his normal troops. These will be immune to Didact's mind-control, since all members of the First Sons are trained to have a very strong will and mind, as they started out as a cult of mentalists (stated by John White in one of the first two games - it's long enough ago that I forget which). What makes the biggest difference, however, are the conduits.

The Aura Conduits make gigantic versions of themselves, which can attack with proportionate force. This serves to draw Didact's and his backup's attention away from the normal soldiers, Kessler himself, and the second, far more dangerous type of conduit in the First Son's ranks. The second kind turn completely invisible, and are armed with shotguns. They can run around and just shoot damn near everyone else in the face with their shotguns with impunity, barring randomly-thrown grenades and other forms of AoE attacks.

In all honesty, if this was just Kessler v Didact, Didact would barely get the edge. Since this is Kessler & the First Sons against Didact & the forerunners, however, Kessler's side gets this, though it's still very close.
