I used Bryce 3 it was my first 3D app and I loved it because I had not seen anything better, then one day a friend of mine showed me Vue and when Vue 5 came out I got on board.  In the real world I sell aquarium products and it's kind of the same thing really. I get customers who have this great pump and think it's the best out there but when they see the pumps we use they realize they had nothing to compare theres to until now. For the record though, I stil have Bryce, I even upgraded to 6.5 but have only bothered firing it up maybe 3 times since I got it. The controls, the UI, the material lab, lighting  all make Vue an amazing and easy program to use. I have become a vue addict and I'm proud of it :)
