Another Rhino plug :) First let me say that I've seen great models from all the apps out there. I started out with Bryce but wanted to try making my own models(tho I've seen some awesome models made in Bryce - Humorix is a good example). I tried demos for most of the modeling apps, but Rhino seemed to be easier get around in. I also used AutoCad in high school so that made for a plus. Like everyone else said it can handle all the details you can throw at it. It's main drawback for ME is the renderer. Also I've tried Lightwave unsuccessfully, but I must say I browse the LW forum everyday(after Rhino ofcourse) and there is always awesome models there...
