Tsunade doesn't belong on this list at all, as her strength is augmented by chakra. We see that even with her chakra-augmented strength she cannot due much more than dent Susanno. That's why she got chopped in half, guys.

THESE ARE ONLY ALIVE PEOPLE, NOT DEAD OR EDO!!!!!!!!!!!!!!!1
How do you figure? To complement Tsunade's natural raw strength she adds to it with chakra enhanced strength.
While it is true that we know, Tsunade can use chakra enhanced strength as she taught Sakura how to use such an ability.

The majority of Tsunade’s strength however, comes from brute strength. How can we know this? In order to realize Tsunade’s natural strength we must look at a few forms of evidence. I will display the evidence in terms of strongest to weakest.
The first reason that we can know that the majority of Tsunade’s chakra comes from her base or natural strength relates back to part 1. According to Kabuto, he cut her Biceps Brachii and the Rectus Femoris muscles when he attacked Tsunade.

His goal was to stop her from using her “enormous strength.” At this point, it is worth noting that both Orochimaru and Kabuto realized that one blow from Tsunade would mean death in the beginning of the fight. Yet, after her natural strength is taken away Kabuto is very much still alive after taking a blow. Which seems to suggest his scalpels did what they were supposed to do. Now, your reply may be, maybe she decided not to use her chakra enhanced strength and that is the reason that he lived. But that does not seem to work as the resulting force from her punch traveled down from his face down his body and to the ground cracking it in several places.

This seems to suggest that she still packed a very hard punch. And chakra enhanced strength not killing him does not cause a plot hole because when Sakura used her strength against Zetsu she did not kill him.

Essentially, a chakra explosion is created. Therefore, lifting and wielding large objects cannot be accomplished through Chakra Enhanced Strength. To get an idea of how heavy Gamabunta’s sword is we will see him use it against opponents near his size because Tsunade used it against an opponent his size. When used against Shukaku, Gamabunta said it was all I can do to complete the swing of my sword.

Afterwards, he lost his sword because he did not have the strength to maintain grip of it. When used it against Manda, Gamabunta was unable to take the sword from Manda’s mouth

Because we are now comparing the strength of Gamabunta and Tsunade, now would be the time for this tangent; to show that Gamabunta is not a weakling. He was powerful enough to hold down the Kyuubi for a short period of time.

Tsunade however, despite being much smaller than Gamabunta was able to completely lift, grip, and maneuver his sword with perfect accuracy whilst jumping much higher than the height of Gamabunta.

Because Chakra enhanced strength plays no role in this we can get a better idea of Tsunade’s brute strength.
