Yeah, I'd also go for the interface of Vue - I think it makes placing lights and cameras accurately much easier than Bryce (but I've only used Bryce 4). I use it to light and render my Poser scenes and find the quality afforded by raytracing generally outweighs the massive increase in render time over Poser's scanline engine. Not that Vue's inhernently slow, raytracing just takes longer. Poser lets you build great scenes, Vue provides the finishing touch, for me at least.
