What makes her stand apart from the other figures you mention is that she is available for both Poser and DS and thus, in theory, it would be easier to make supporting items for her that serve both worlds. Rigging systems may be different but a geometry facet is a geometry facet, a morph delta is a morph delta and a texture map is a texture map. The other differences between Poser and DS systems are mere  administration and should be open to automatic conversion. 

Somehow however this is not capitalised on in the communications so I am not sure about the value in practice.  

The face is plain for easy character morphing. The body looks realistic and is easy to play with. She takes Victoria poses quite well.
