how powerful vegeto was compared with ssj3 goku?

its base vegeto

Goku(kidbuu saga)

I think he was

5x -10x ssj3 goku.

.

He went from being many times weaker than Buu and Gohan to effectively stomping them simultaneously.

@SheenLantern: cant he do that with 3or 4 x power?

Considering Vegeto was just playing around him Buu when he was fighting, we don't know. We haven't actually seen him serious to judge his power.

@brainstorm01: Okay.

gohan as ssj 2 <2x goku or vageta. But still he made perfet cell look like nothing ,what p.cell doing to vageta.

So we can say he was around 1.5 x vageta or goku

Then maybe m gohan>superbuu>ss3 goku but none of them was 2x ssj3

This way we can say with 3x ssj 3 or more vageta can do that to buuhan what he did.

goten said to be more powerful then friza so let just say he was equal to ssj goku (pre cell saga) then he became on par with ssj3 goku.

This means he became 2*4*2*2=32x

This makes vegeto at least 32x ssj goku(kid buu saga)

While ssj3 was 2*4=8x ssj

So vegeto was clearly around 32/8=4-6X ssj3
