Raiton - Gian solos U_U realistically speaking it has more depth than sasukes chidori variants, kakashi's double raikiri barely stalemated it Lol, the raikages only shroud themselves in lightning chakra, Lol Hiruzen's jutsus are pitiful that old mongrel is way too overrated
Doton - Lml Domu is wayyy better than that big nose's earth sandwich or whatever it was, it's an overrated technique U_U, manga has shown that Kakuzu is a master of doton manipulation as evidenced by Kakashi's statement so... and ofc Onoki hasnt been portrayed as a master either and Domu solos rock golem easily U_U
Fuuton - Lol Atsugai is a gigantic jutsu my man, dont know why danzo gets hyped up so much when clearly kakuzu would have done more damage if he had that elephant's suction power >.>, i suppose we can keep naruto at one but Kakuzu can stay at number 2 U_U no way is temari better than he is.
Katon - Ehhh i'll give this to Madara and Obito with those juubi katons but Kakuzu's jutsu is a gigantic fireball erupting from the earth my man, better than anything jman has done especially sincw he needs oil to make his katon look good U_U and its size is overrated too gamabunta isn't even as big as those gigantic trees Kakuzu was fighting around :|
Suiton: Kisame takes it easily Kakuzu is featless here but if he showed a water jutsu it would have been on a pretty big scale my man ^_^ probably equalling or being larger than Meis... Yeah... And above pitiful Hiruzen and Tobirama U_U
