He stated that Indra's arrow was his strongest attack for the time being, implying that he eventually had a stronger one up his sleeve that he could not use (due to inexperience with Hagoromo's power)
By the end of the manga Sasuke was finally able to combine his Enton with his raiton, a feat that Kishi decided not to give until he completely ran out of chakra.
Being able to combine lightning with Enton suggests that he could eventually do the same with Indra's arrow, and if Amaterasu is considered the strongest physical attack
Then logically an Enton Indra arrow would be the strongest offensive jutsu in NV.
This is not a jab at Naruto but based on what we've seen I think Ashura's main power lies in his absolute defence and Indra's main power lies in his attacking ability. So although Sasuke may have the strongest offensive jutsu Naruto would still be able to tank it.
