Goku would win. Him blasting Kid Buu off the face of the universe helped solidify that he is really one of the best fighters in the universe. I don't give a f*ck what anyone says. He defeated a psychotic little pink bastard that has destroyed solar systems(destroying f*cking Earth and all of humanity too) and is literally pure evil and whose only thought is to kill. That's pretty badass.
Justice. Crime can not be tolerated. Criminals thrive on the indulgence of society's understanding.
