Form-factor, features, battery life, for some people the screen, etc. It doesn't "crush" the Moto X at all unless all you do is stare at a spec sheet. I didn't say anything about it being well-known, either. I'm speaking of overall which phones are better.
If you want to talk about features, battery life and screen, the Galaxy Note 3 "crushes" all phones currently out there. Form factor is very much in the eye of the beholder. I think the Nexus 5's form factor and build quality are top notch.
