Shino wins.
Speed feats: insects sneaking up on zaku from chunin exams in just 2 panels, while no one else saw until it was too late...pretty impressive seeing as though they were in an open area, and the bugs remained hidden until the last minute.
besides, Kiba may be fast...but that's all he has going for him. Shino actually uses clones, including substitution jutsus. if anything, kiba would be running from the insects...
shino wins, no competition
just think, if Shino used the move he did on the game (Parasitic Insects: Hailstorm)....THAT would be OP! *sigh* such potential
