Rayquaza.

He has more powerful attacks like the Hyper Beam, he is more faster meaning he will be able to dodge most of Alduin's attacks, and is more stronger then him which will help a lot. In all Rayquaza has more better attacks and more powerful then Alduin and the X-Factors of Speed and Strength will help out.
