I think there are things each program can do better. For me though, the number one reason would have to be versatility. The number two reason would be stability. Bryce is a rock! :) That versitility translate into the abiltiy to do fantastic abstracts all the way to photorealistic. To me Vue pictures do not seem very real. They look more like realistic paintings then photo's, with Bryce you can do either. If you are looking into getting either program my suggestion would be to spend a good amount of time looking around the net at galleries for both programs. I think that after a few days or so you will see the versitility I am talking about. There are many more reasons I pick Bryce, too many to list here things like higher resolution terrains and others make it a long list. For you that list maybe different, each of us have different requirements in a program. Give the demos a whirl (Bryce's demo is hobbled with a slow renderer), Vue doesn't have a demo for ver 4 yet but has one for 3.1. Griggs
