I've got vue and bryce. I hardly use bryce though because I've found it easier to get good results with Vue.

It may be that I haven't had the patience to get into bryce.

Modeling in Vue5 is something I havn't tried I tend to import models from else where. You can create primatives, group them together and use boolean logic to get difference, union or intersection. It also has metablobs but I've never even looked there.
