WB has an ugly user interface in my opinion - its primitive and hard to come to grips with like mid 90s versions of Autocad for Windows 3.1 (thats what it reminds me of!) - both Bryce and Vue are way ahead on user friendliness. Both Vue and Bryce have gorgeous procedural textures but Vue it seems to me has the edge on user control and fine tuning of these things. (Not something you pick up straight away.)

My subjective opinion is real simple - I got Vue because Bryce renders look like Bryce renders whereas Vue has the potential to look more realistic if that is what you are after. Don't get me wrong - Bryce renders do look gorgeous in their own way but they are kinda too clean and too metallic looking if you ask me - if you examine a bunch of landscape renders you can usually pick the Bryce ones - to me that didn't seem a good thing. (Sorry - told you it was a subjective opinion.)
