Who is stronger vegeta or Goku

Goku is definitely the stronger fighter. He got to super saiyan 1 3 and 4 before him and Vegeta had to cheat and have Bulma make a Beam and for the person who answered before me if i recall correctly isn't Vegeta the one who let Cell get to his Perfect form? And I'm also pretty sure that Vegeta at one point or another was a "Bad Guy" Like in the Vegeta Saga and The Majin Buu Saga so you clearly need to do your research.
