I have Vue and Bryce both, but only use Vue. Vue will allow you to do a 7200x7200 (or greater) render at up to 600 dpi with complete control over the aspect ratio and level of anti-aliasing. It also renders to screen or to disk (get the free patch or the disk render might not work). Renders can also be farmed out to other machines on the network. Vue renders very well, especially with volumetric effects. You might want to look at the Vue and Bryce galleries here at r'osity.
