I never understood Blender, Anim8or, or Amapi, but I didn't really try them for long. I got the hang of trueSpace 1 after a while, but the changes made to the interface in recent versions aggravate me. By contrast, I dived right into MilkShape. The simplicity of the interface appeals to me. I'm looking forward to version 2.0. Well, back to Paint Shop Pro. Stay tuned for further developments.
