Sasuke tried to match Naruto's power by absorbing the chakra of the other Biju, but Naruto denied that advantage with Nature energy.

It's not clear how much Nature energy Naruto could absorb, but we've seen from Sage Training that it's about 1/3rd to half your reserves. If Naruto could balance all his Biju plus his own chakra for Nature energy, that means his power increases by another 50%. And that assumes he didn't get the ability to absorb significantly more Nature energy with SPSM, as the Juubi itself was Nature energy and could absorb massive amounts easily.

Besides since his Indra's Arrow was matched by Naruto's jutsu, it's clear they were evenly matched with power.
