Imports: Bryce does a better job importing .obj files. Vue has an object heirarchy which makes picking out items in the scene infinitely easier than Bryce. (If you import an object with multiple parts, it is easier to work with a part of the object than Bryce.) Materials: There's tons more materials available for Bryce. Vue is a bit easier to create materials for. Vue does have problems with materials with transparency. They say more than 6 transparencies causes a problem, but I've had the problem crop up with just 1 light and 1 transparency. Modelling: Vue is slightly easier for Boolean modelling due to the object heirarchy. Each has a terrain system where you can create models by elevation. I'm horrible at modelling that way so I can't tell you which one does a better job. (Can't do it in Bryce, can't do it in Vue. Comes out pretty even for me.) Rendering: Bryce gives a crisper look than Vue. Vue gives a few more options for outputting the final effect. Lighting: Bryce beats out Vue, IMO, in lighting. Bryce has volumetric lighting. Vue does not. It is a pain to try to fake it in Vue. It's been a while since I've used Bryce much, but Vue lighting seems to be lacking. Usability: Both are fairly intuitive for getting started. Bryce and Vue both have functions that are not immediately obvious, but I've stumbled over more in Vue than Bryce. The Bryce ones I found out from others. Manuals: Bryce has a bigger manual which covers more stuff. Neither manual was terribly readable for me. The Vue tutorials didn't explain things well enough for me, and Bryce would say things like, "Yes, we have polarized raserosity, click this to use it" with no explanation of what polarized raserosity was or why you'd want to use it. (No, polarized raserosity doesn't exist, to my knowledge, but I don't have the manual directly in front of me.) If you need more info, let us know.
