I'm very happy with Vue - but keep in mind with my 2-cents comes the fact that I don't use native Poser files. I create objects in other apps (Poser, C4D, XSI, Mudbox) and then import them as OBJs.

I also do a ton of post work - all my particles, heavy lighting effects, more intricate texturing, etc., are done in Photoshop CS3 and After Effects - so again, I limit Vue to an assembly renderer for my objects. I find the lighting tools fantastic and easy to use, and I love that V6 finally has Gizmos to grab and move EXACTLY to one direction, or all if you choose - this makes things MUCH easier to align.

Long renders aside (but they're shorter than Bryce!) I get the results I want form Vue.
