I've been using Vue since version 2 (which is now available free) and it is extremely easy to use, much easier than Bryce (I've got Bryce, too, but it is so awkward to work with, I never use it.) Of course, your mileage may vary. There are a lot of Bryce-users who have tried Vue but stuck with Bryce. To each his own. If you've worked with the demos of both programs, it will give you a better idea of which is best suited for your particular tastes. As thip mentioned, all software has bugs. When Vue 4 was first released, it had a lot more problems than anyone expected (even E-on!) but the customer service can't be beat. They've been working on it diligently and the 4.03 has cleared up most of it. :)
