The vary of energy between Kurama and Shukaku could be from 16% extra for the 9-Tailed Beast to as much as 24900% extra, relying on how Hagoromo Otsutsuki did the division of powers.

But since the power of the tailed beasts is measured by the number of their tails I could say that the eight tails is stronger than the nine tails if orochimaru did not release the technique but since he did then the nine tails is much stronger.

Even with half its strength, it could overpower five other tailed beasts, destroy Madara’s senjutsu-enhanced Susanoo, and battle Sasuke’s Tailed Beast-enhanced Complete Body – Susanoo.

Kōjin (コージン, Kōjin) more commonly known as the Eleven-Tails (ジューイチビ, Jū-ichibi) is the only known artificial tailed beast in the ninja world.

Fans remember Gaara losing his ties to Shukaku during Naruto: Shippuden as he was the first Jinchuriki captured and sacrificed in order to summon the Ten-Tailed Beast. The story follows Naruto, a young ninja with a sealed demon within him that wishes to become the leader of his home village.

Naruto Uzumaki
Naruto Uzumaki While that’s a hot topic debate between him and Sasuke, it’s still easy to admit he’s by far the strongest jinchuriki.
