Isnt it 3-0 after all he wins against Goku in:
The Saiyan Arc, The Majin Buu Arc and Superhero BUT There are a ton of mitigating factors to this:
First If Goku Fought Vegeta at almost any Other Point he wouldve Won!
Second Vegeta Fought dirty in 2 of those
and third in Superhero they break both their Characters You dont believe me? Who was the first who used Image Trainning and Ki Control Goku!
And Who throws wild Punches and Ki Blasts Vegeta! If they were Written right Goku wouldve Stomped Vegeta!
