I saw it as Alduin was defeated because he strayed from his duty of devouring the world at the end of time. Dragonborn was created to stop him. If Alduin had reached full power and by the time he started eating the world, he will be invincible even to Dagon.

If we are talking about in Skyrim main quest, Mehrunes Dagon is stronger because Alduin is not at full strength. I see Dagon as a Daedric Prince/ Evil God who exists to try and conquer Nirn. He will be more equipped and suited than Alduin in conquering Nirn than Alduin if they were to compete against each other.

If we are talking about both at full strength, you can't really top Alduin who exists to end everything, Mundus, Oblivion, Divines or Daedra.
