Ever since the Momoshiki and Kinshiki appeared in Boruto. fans have been debating whether Sakura or Kurotsuchi has the strongest push. Both female characters have monstrous strength however, we are going to discuss which one of the two characters has the strongest punch.
Many people would agree that Sakura could easily outclass Kurotsuchi in punching strength. However, Kurotsuchi does have a strong monstrous punch but it is not on the same level as Sakura’s punch. Sakura’s punches and strength have been improving ever since she harnessed the 100 times healing Jutsu. All her punches now cause a shockwave effect and this was evident within the Momoshiki invasion.
However, for Kurotsuchi even more, so punches do not rival Sakura’s ninja war arc punches where Sakura replicated what Kurotsuchi did but made her target hit go further and then followed up with an outrageous monster punch even stronger than an earthquake.
Nevertheless, both characters are pretty strong and both lean from the same master while comfortably sitting at Kage level. However, Kurotsuchi IMO is low Kage level while some such as Sakura is mid-high Kage level.
Let us go over their feats and skills.
Kurotsuchi
Kurotsuchi in Boruto was able to tag Kinshiki off-guard and sent him flying which is very impressive. Kurotsuchi was a Kage-level fighter that has a variety of Jutsus on her side while using her sealing trademark Jutsu the impressive lava release. She is also a pretty good taijutsu fighter.

Sakura is a very strong Kage-level fighter and she punched an off-guard Otsutsuki called Kaguya which in turn bruised her cheek and broke Kaguya’s horn. That one punched same the entire shinobi world and was more than what Kurotsuchi could accomplish on a much weaker Otsutsuki such as Kinshiki. Sakura has casual monster strikes that can cause large AOE damage. Not to mention Sakura can also summon Katsuyu to continuously heal herself, spray acidic juice, and defend her as well. Lastly, she was able to tank Shinra Tensei and can heal any wounds quickly like her predecessors Tsunade and Hashirama. And Sakura is good at taijutsu as well.
Sakura in Boruto now is stronger and faster, she can even easily tank anything Korutsuchi throws at her. Kurotsuchi got defeated by Ku although he was pretty strong. However, it is a disappointing feat for a Kage-level fighter, she apparently did nothing to him which really made a lot of us question why the writers even did this fight.

Sakura or Kurotsuchi Who Has The Strongest Punch?
Sakura has the strongest punch over Kurotsuchi. Sakura overall has better feats and the right arsenal to take down Kurotsuchi’s speed and power. if Shaura gains the oppertunity to get close and strike Kurotsuchi just once with enough force, Kurotsuchi is done for. However, it’s not a complete stomp because Kurotsuchi would still hold her own thanks to her long-range Jutsu. Overall, Sakura is the superior of the two because Sakura possesses the 100-time healing Jutsu on top of the monstrous strength.
Both Sakura and Kurotsuchi are very strong Taijutsu fighters and probably could take out each other if given the chance. However, Sakura holds the title of the strongest female Kage level puncher.
