Poser's biggest advantage is the vast amount of content available for it. It has an edge to other 3d software for poser figures can be reused over and over again, sold and reinvented. Poser figures are user friendly and available to the common joe  that anyone can create his/her own movies or artworks. 3d before is an elitist craft where one should shelve thousands of dollars just to get the software and the school course to learn it. Now anyone with a few a hundred bucks can get the software and a small budget can get himself a neat poser content. Vue and the rest of the 3d softwares don't compete with Poser but works hand and hand and enhances it.
Just imagine the time you save using ready made poser content than to redo the whole rigging and modeling.

Passion is anger and love combined. So if it looks angry, give it some love!
