Round 1 Vegeta, without a doubt. Recorded power levels put Vegeta over Goku by a good bit.
Round 2 I feel inclined to say Vegeta. Im assuming youre including all the zenkai boost Vegeta received on Namek, meaning the one he received after his fight with Zabron, the boost he received after his fight with and finally most importantly the one he received after Krillen nearly killed him. Therefore Vegeta was somewhere around Frieza's base form where Goku was above Ginyu but not in Frieza's league. Without his final boost then Goku.
Round 3 Is Vegeta. Though it's never explicitedly stated or explain but it's heavily implied that at this time Vegeta was stronger than Goku at this time. Vegeta's base form was stronger than Goku's and he was literally killing himself trying to become a Super Sayain.
