I use both Blender and Poser, Blender much more than Poser for pretty much everything except... posing figures. This is where Poser really shines. To set up a scene like the attached in Blender is certainly possible, but it would take so much more time (rigging the figure, for example, would be a massive undertaking!) that one would lose track of the original project objective.

Someday, Blender's rigging capabilities will mature (they're not bad now - with Rigify - but still) to a point where one can dispense with Poser altogether. No question that in terms of materials and rendering, Poser can't hold a candle to Blender.
