¿Who is stronger, Zamasu or Gogeta?

Originally a Kai apprentice from Universe 10, Zamasu becomes disillusioned with mortals, leading him to enact the "Zero Mortals Plan" to eradicate all mortal life. He collaborates with his future counterpart, resulting in the creation of Goku Black by swapping bodies with Goku. Their fusion through the Potara earrings forms Fused Zamasu, a being of immense power but with a deteriorating body due to the fusion of mortal and immortal entities. Zamasu's abilities include energy projection, flight, and a unique form of immortality.

Gogeta's debut occurs in the 1995 film "Dragon Ball Z: Fusion Reborn," where he confronts the villain Janemba. In this appearance, he showcases the Super Saiyan form. Later, in "Dragon Ball GT," Gogeta achieves the Super Saiyan 4 transformation during the battle against Omega Shenron, displaying immense power and a confident demeanor.

In "Dragon Ball Super: Broly," Gogeta returns, this time attaining the Super Saiyan Blue form to combat the formidable Saiyan, Broly. This portrayal highlights his strategic prowess and combat skills, solidifying his status as one of the most powerful characters in the series.

Gogeta's techniques include the "Big Bang Kamehameha," a combination of Goku's Kamehameha and Vegeta's Big Bang Attack, and the "Stardust Breaker," an energy attack designed to purify evil.
