The thing is, if you take Dawn, V4 or Antonia and texture with the same care and render as the model from Turbosquid you will get just as good "realism". Daz and Poser should be used for Posing, that is what they are good at that is what they do. The polygons and morphs are good as they are. When you shoot you must aim in the right direction.

But art is not realism.

"just a hint of a hand-created element can activate a surface, instill passion and energy into a medium, and reassure the recipient that human understanding and insight are the foundation for the message.”
