Poser Pro 2010 advantages:

• Runs the executable (scene setup, etc) in 64bit, and most important, it renders in 64bit, so you can bring lots of RAM to bear.
• Extra capabilities in import/export of geometries (Collada, etc.);  important if you model.
• Render in network, applying all of your computers to a project;  great for rendering animations.
• Gamma correction rendering
• Fusion with high-end studios
