Ok time to bring the ultimate battle of DBZ fanboys on here.
Who is the stronger one ? Ultimate Gohan or SSJ3 Goku
I say Goku and there are reasons why.
The powerscale of Goku's transformation showed his SSJ3 form is on a higher level then Ultimate Gohan :D
And also, people have to remember that he didn't become SSJ3 in a living body, so everytime he turned SSJ3 in a living body, it put strain on him. ^_^
