"I will let you decide which looks better."

I know you mean well, but based upon what render settings and lighting in Carrara? ;)  If you choose settings in Carrara that don't match up to the Poser render then you simply need to adjust your Carrara settings ;)  There is a learning curve to it, of course.  I don't do stills much, and it's a pretty broad topic.  There are lots of threads in this forum and others that could be of help with your render/lighting settings in Carrara.
