Putting this to rest finally. Not a diss thread either.
Rasengan and Susano'o both are made from chakra. One offensive . One defensive.
Perfect Susano'o was compared to the power of a bijuu.
Multiple rasengans defeated the Kyuubi .
1. So multiple rasengans stronger than Ps.
Madara's Susano'o is stronger than Sasukes.
Naruto's rasengan variations stronger than Minatos'.
2. So Naruto's rasengan variants could trump sasukes susano'o
Susano'o has been shown to be weak against wind techs.
Naruto specializes in wind techs.
3. Wind style rasenshuriken from base,,sage,Km or Bm would destroy susano'o
Susano'o covered in Amateratsu is a stationary defense which might blind the user.
Rasengan variants could attack from any direction without the user getting touched by black flamed
4. Rasengans can protect the user from direct contact while attacking.
Madara's susano'o coupled with the rinnegans preta path =ultimate defense
Sasuke doesnt have rinnegan or perfect susano'o
5. Naruto has Bijuu mode which is stronger than regular susano'o
