So if its between Goku as he is now, then he wins, no question. Saitama, assuming that attack Boros used could destroy a star, though I think its more of a planet busting attack just from his statement, Saitama would be at least Star level. Goku however, in his God Form, his punches shook the universe. Even if you don't agree with the idea that Goku during his fight with Beerus is universal, Goku still would have destroyed half the universe in that clash, which is still far more impressive then Saitama's punch. Speed also easily goes to Goku, due to being able to keep up with the likes of Beerus and Whis.

But you said this was Saiyan Saga Goku. If it is, I'd say Saitama would ultimately win. Goku might give him some trouble but Saitama I think would have the power edge enough to grant him the win.

So that's my prediction.
