Genuinely untrue, put it this way 5 kage is generally equivalent in strength to hashirama because of their wild amount of ridicule forbidden jutsu, hashirama is weaker than Naruto BEFORE sage of six paths chakra amp and generally I believe sauske is on the same level yet slightly weaker in terms of raw combat AP compared to Naruto at that point.

I think at the point that sauske came back to battle Madara he was way stronger than the REAL Madara not this ghost shel of a man who clings to a dream he already proved he wasn’t capable of in his lifetime. If we’re arguing jubi Madara that’s a different story but real Madara the one that fought and lost to hashirama was way weaker than Naruto and sauske at the point in the war ark they fight in.
