Bryce is more full-featured and user-friendly. And the texture & terrain engines are simply the best around. It does not, however, do greenery very well. Many people have come up with ways to 'fake it' to get trees, bushes, grass, etc. but it IS more work. Vue handles greenery better... it even includes some built-in tools for handling that stuff. Renders are faster, but IMHO of lower quality, although I think it does support soft shadows (wish Bryce would do that!). Also, the user interface is a bit obscure, and the textures/materials are ho-hum. Vue is earlier on in the product development than Bryce... if they continue to develop it well, it could become much better.
