They are strong, but not much as fanboys would like by this I mean the amount of chakra those attack had is not that huge as fanboys think.I am referring to Indra arrow vs FRS and Futon TBB attack.
Now people are saying Naruto absorbed large amount of nature energy so his attack was extremely powerful and Sasuke Indra arrow matches that.
Thats not try let me remind you that you must balance nature energy with your own chakra .
As explained in scan above you can't use too much or too little nature energy , you must use same amount as amount of chakra you have .
Now Naruto that absorbed nature energy before clash was already low on chakra ,so amount of nature energy he could mix was limited and low.
So Naruto attack didn't contain that much chakra like fanboys claim and same goes to Sasuke Indra arrow which is equal to Naruto attack.
