If you understand the function editor and use the Pro version of Vue, there is no way to put Bryce in the same category.

I also started with Bryce and still have it, but it does not compare nor should it. Bryce is free and with Daz Studio being free also, for a hobby you can produce some great stuff without buying Poser Pro or Vue.

To answer the question, if you are serious, can afford it and are experienced in rendering or 3D in general you only have one choice; Vue. If you go Infinite the only real limitation on what you can do is your skill level in the function editor and with lighting.
