The main character in both are half demons whose father is so powerful it's stupid. Inuyasha and Rin are very similar in personalities and both have befriended a powerful priestess.
The real difference is the motive of the antagonist. The antagonist in Inuyasha (Naraku) made it very clear what he was after early on. The antagonist in Ao no Exorcist hasn't even been fully revealed yet let alone his motives.
If you like one, you will definitely like the other
