This is the Poser 5 version of my Assassin image in my gallery. (I did it for an article on poser 5.) It took a little less time to render than the corresponding image in Bryce, but it's also simpler, the hair notwithstanding. The Bryce one has reflections and transparencies and about double the number of lights. And Bryce has much better control over lights, the scene can be built and seen easier, the final render usually looks better, and so on. But with the hair, collision detect and cloth simulation, Poser 5 also gives something more than Bryce.
