Naruto and sasuke would wreck Indra and ashura
Ashura doesn't even have the power of all bijuu unlike naruto and unlike naruto who has the chakra directl from his father, his chakra is nowhere near as potent
And Indra doesn't even have te rinnegan, and his chakra is not as potet as sasukes either meaning his susanoo isn't as powerful
Either naruto or sasuke can solo the sages sons by themselves
