We had this one the other day. Chouji's butterfly bomb and chakra attacks are able to gust away and sheer-force bugs into destruction, especially if this is Gaiden Chouji at base. Remember, this is base for Chouji nowadays.

Otherwise the match ends fairly quickly if Chouji doesn't go to mountain-size. Where seismic waves prevent any normal human (and especially) flying bug to appear. Shino can mess him up fairly bad with his summon but when you put it into perspective that's still just the size of his foot. Could go either way since base but i'll still back Chouji if he gives it 101% Kakuzu, Asuma and Hiashi were all smarter and tougher opponents IMO.
