Well, the the manga has stated that kekkei tota is stronger than a kekkei genkai user, i mean not always stronger of course. Kekkei Tota is the combinations between three elements and its way stronger than kekkei genkai, kekkei genkai have only two elements combined each other.
But to the point, how can Jinton defeat Hashirama's Mokuton, well Jinton can destroy Mokuton with an instant cuz og the scale and explosion. I'm not talking about Onoki or Mu vs Hashirama, now I'm talking about can jinton defeat Mokuton?
Easily, but the user would have to be a fu*king monster to have enough chakra to create a jinton big enough to destroy Hashirama's Shinsusenju.
This, well mostly. It would really depend on how big of a chakra pool each user has. A jinton user with a small pool would be utterly destroyed by a mokuton user with a big pool. But if they were even, it'd be a toss up, I think. Mokuton seems to be just too overpowered and useful. Where as Jinton is just used for massive attacks.
