They are both strong, but if you want to know who is stronger, they acutally fought. The fight ended in a draw. A few episodes later, when Vegeta realized Goku could have turned into SSJ3 and beat him down, he got mad at Goku for having held back. So the answer is, Goku was tremendously stronger at the time although he withheld his power to give Vegeta a fair fight.
