There are things that Bryce does well, and things that Vue does well. I have both, and actually started in 3D with Bryce 2. Upgraded through Bryce 4, and when 5 came out, I noticed Vue 4. I tried the demos of Bryce 5 and Vue 4, and decided that Vue 4 was better for my needs. I have since upgraded to Bryce 5, but I won't lie and say that Bryce 5 is my first choice. I use both, and both have their place.
