So, let's see...

With all the powers at his disposal, Moldy Voldy takes this one. In short, he is far more versatile than Aang, who is limited to manipulation of four forces, however creative. Voldy can use a much wider array of powers, and can use apparition to dodge Aang's attacks and blindside him with a counterattack.

Voldy wins this one.
