Each has strengths and each has weaknesses... Although the new vue d'esprit is going to be a great program, the new bryce kicks some serious butt, so I would go with both... You may find the interface on vue easier, if that is holding you back... File export, I don't know what they have planned for vue... Render is supposed to be faster than before, but I don't know if it's faster than bryce.. system requirements are probably going to be about the same for advanced features... Price should not be the determining factor... You can do some really great things with Bryce 4, and honestly speaking, upgrading to vue for $169 is not what I consider a bargain... You can probably get it new for $179 at some places that sell it on the web... I will probably get vue 4, because I like it personally, but I will definitely get bryce 5 because I know it better,...
