It's too early to make a final decision from the information available. I will probably anyways end up upgrading both. Then I will upgrade my "Bryce vs. Vue d'Esprit" comparison on my website ;-) In this comparison I reviewed Bryce 3 and Vue 2 (because I think that the upgrades Bryce 4 and Vue 3 were not really big moves). I hope that there will be some more improvement in both programs. I just ordered the Vue 4 upgrade...
