One thing that made me fall in love with Vue is the object list on the side of the program. Now that I'm making models with various parts, if I render them in Vue, I can easily pick an individual part and give that a material. It took me months in Bryce to figure out how to select a part of a model, and even then, it is more cumbersome. The Bryce manual is bigger, but it's not easy to understand. Vue's manual is easier to understand, but it's organization leaves a bit to desire.
