SolidThinking for 3D

Has anyone here used SolidThinking Vantage on a Mac G5?

I know its more commonly used in Europe, and is newer software, but I’ve heard really great things about it for 3D modeling.

How does it compare with 3DSmax/ SolidWorks/ Rhino on PC?

Or, have you used SolidThinking on a PC, and what is your experience with it?
