Answers.Text: Well, the difference is that you have more firepower on c3. In your variation white can take on d6 because he can easily defend the Nc3 after Nxe4. But with the bishop on g7 after Nxe4 the Nc3 is already attacked three times.

Answers.Body: <p>Black gets his pieces to attacking posts after cxd6. Nxe4 is a good reply and Black threatens to take multiple times on c3. The extra pawn isn't that important compared with the relative quality of Black's pieces. Bg7 Nc6 and Bg4 are coming with good development and chances for the Black player.</p>

Answers.Text: That would be correct if the black bishop was already on g7, e.g. after 1.e4 d6 2.d4 Nf6 3.Nc3 g6 4.Nf3 Bg7! 5.Be2 c5 6.dc5 Qa5 7.cd6? Nxe4! In the variation given by the OP, however, 4...c5? 5.dc5 Qa5 6.cd6, the normal move 6...Nxe4 meets the strong retort 7.Qd4! which protect c3 and attack both the Ne4 and the Rh8.
