So which is Google's realization for Android? The Moto X? or the Nexus 5?

When the Moto X came out, I heard people say that it was Google's realization of Android designed to compete with Samsung's version of Android (ie touchwiz). But now, the Nexus 5 is out, and it was what the Moto X stood out for: always-on listening. That makes the Nexus 5 just as good, if not better, than the Moto X. But which of them is what Google really wants Android to be? (Both is a valid answer, it's what I think, but I want to know if there are any out there in the Motorola camp)
