To basically agree with most people here, Oren is the strongest Sengoku Driver user, ignoring the Jinba forms (because that's a combo power deal, not really just the Sengoku driver at that point) and Kachidoki (because Super Mode cares not for your ranked lockseeds :P). So far we've yet to see Kouta actually beat him without upgrading to a higher mode, so Oren's still king of the Sengoku riders. Solo, at least.
