Vue beats Bryce hands down in: 1. Ease of use 2. Customer support 3. Speed 4. Vegetation 5. Poser Imports 6. Terrain editor 7. Material editor I think they tie in render quality (although I haven't seen Bryce 5). I've used Bryce 4 for a year now; got Vue last week and haven't loaded Bryce since. Can't see any reason to.
