Blueprints are a toy. Which serious Unity dev would use UE4 without C#/F# or UnrealScript!?

Clearly, the popularity or to be more precise, the user base of Unity and others engines compared with engines like UE4 and Cryengine has nothing to do with the system requirements necessary to run them. I mean, only because Unity can run pratically in any computer/laptop, while UE4 requires at least a middle/top level setup, has nothing to do with that, right?

In terms of system requirements, both UE4 and Cryengine are close. Cryengine has scripting languages, so which is more popular, UE4 or Cryengine? Or which one is getting more attention?
