I couldn't make hide nor hair of Wings3D. I tried it, but even with a tutorial, I couldn't do anything in it. Anim8or, OTOH...I found that very intuitive. I was building things immediately, without really needing a manual or tutorials. But I came to 3D from CADD, so YMMV. But I think anyone who's used to engineering/drafting 3D apps will find Anim8or very intuitive.
