Well rockets I don't own Poser, so I can't speak to it's interface with Vue, but I do own Bryce 4 and I can tell you from personal experience that Vue is much easier to use. The interface will startle you a bit at first but once you've worked with it you will love the split screens and the ease with which you can work with textures. It is much easier to "move around" in Vue (I find trying to work on interiors in Bryce to be a real nightmare....sort of like roaming around blind!). The split screens make Vue much easier to move from room to room.....better camera control. The atmospherics are much better in Vue, making for more "life-like" output. And it renders a lot faster than Bryce! Anyway, I would highly recommend Vue. It is a much more user friendly program than Bryce 4.....and yes, by all means, download the demo and try it out! The little jump start tutorial will have you going in no time :) Plus, there are a ton of folks here willing to answer questions.
