I think people underrate the god tier's power levels because of DBZ nostalgia.
That being said, there are a lot of others that completely exaggerate them.
IMO, we have absolutely not seen naruto/sasuke's upper limits of sheer destructive power. I believe that (in tandem) the two of them have moon busting potential. That being said I think I rate them each around 220-250 individually, and anywhere from 285-330 as a collaboration (which I believe COULD be enough to take out the moon, and is even likely to occur during The Last if you think about it).
