the reason i came to this conclusion was because of a few things
1) in his prime he was Known as the god of shinobi across all the land
2)using the next generation surpasess the previous thing he was the prize student of the Tobirama and Hashirama , and the later bested Madara at full Power
3) He was revered as the strongest kage alive at the beginning of Naruto even in his old age
4) He beat orochimaru who at the time was close to full power and using impure world resurrection
5)he makes fire and earth look so damn god
You could even argue that he was the strongest shinobi ever or very colse to the top Defs in the top 5
NB!!!!!!!!!(THE SAGE OF 6 PATHS IS AN EXCEPTION AS HE WAS LITERALLY THE GOD OF SHINOBI )
