Judy comes with Poser 5 from what I understand. Victoria and Stephanie are different models from Daz3d. Arizona and Daelyn I don't know about but I bet they are a character morph for Victoria , Stephanie or Judy. Victoria comes in 3 flavors. Vicky 1,2& 3. I have Vicky 1&2 and they are great models. I here lots of good things about Vicky 3 though. If you really want to get some opinions on these models ask in the Poser Forum. I have never used Maya but it is a profesional level piece of software. Also, I here the learning curve is kind of high on it. The movie FINAL FANTASY: THE SPIRT WITHIN was made with Maya. Thay have a Maya forum here if you have any specific questions. I'm sure they would be glad to help. Good luck and have fun. :)
