So how powerful are they, exactly?

[TyrionUchiha]

We see Naruto as the 7th Hokage and Sasuke as a free-roaming nomad...

...but how powerful are they? Are they up there with Madara and Hashirama? Yes, no?

 

[Zealotic]

Weaker than Itachi.. hope this helps you

 

[HENI]

stronger than them

 

[Gerkak]

They are far above madara and hashirama

 

[Elodin]

They surpassed Mads and Hash brown ages ago.

 

[AlphaScythian]

Mere kids in face of Lawd Obito.

 

[Rikudo Madara]

They surpassed Hashirama and Madara eons ago so they're pretty strong. lol

 

[Holy God]

They're way passed Madara and Hashirama in their first lives. They're only below ten-tails hosts now, excluding Obito(Kaguya, Hagoromo, and Madara).

 

[SakuraHarunoHaterSlayer]

Naruto is a bit stronger than Sage Mode Hashirama
Sasuke is a bit stronger than Edo Rinnegan Perfect Susanno Madara

 

[SupremeWater]

you dont understand that Naruto amd Sasuke are the 2 strongest ninja's now , and will ever be even surpassing kaguya , beacause they have the power and knowledge of that power level

 

[LogicnoJutsu]

They Surpassed them the second they came back from death.

 

[Transcendence]

...

They surpassed Hashirama and Madara the moment they were "revived". Prime Naruto and Sasuke (aka 27 year old versions) are so far above it's not even funny.
