I started with Vue 3 a few years ago and have also tried Bryce 5 (which I quickly disliked because of the not quite intuitive interface and the difficulties I had in creating new textures (compared with Vue anyway)). Right now I work with both Vue D'Esprit 4 and Vue 4 Pro, So far I love the added features of Vue 4 Pro, but you'll have to weigh it yourself as Vue 4 Pro is more expensive. Personally if I had neither and had to pick one I would choose Pro over D'Esprit and do feel that the added features are worth it, but only if you don't have either version right now. Just my opinion.
