Poser 5 has a great rendering engine! It produces ray traced images that look great now, much better than the old P4 engine. As for the animation, Poser does animation well. Using vertex and metaballs you can create realistic organic forms in Carrara. Setting up a poseable figure in Poser then exporting the model again to animate it doesn't make sense to me. If you have the new Poser 5 or Poser 4 with Pro Pack you can bone to your hearts content in the Set Up Room. If you don't have the afforementioned there is a text based method to convert a model into a poseable figure as well, it just takes longer.
