I like the Azure Gondra MUCH more than the Rose.
I'm not a fan of the Iluvu so no opinion there.
The Zenirix is my personal favorite. I prefer the natural colors but of your choices the Azure is by far the best.
The Rose Paor is kinda cool.
The Lime Meragon is possibly the best of all the Meragon color options. It's pretty cool.
Roditore's are cool looking pets no matter what color you choose but I kinda like the Magenta for this pet.
I don't care for your color options for the Myotis. I would wait until you have a Cream, Silver, Ginger or Albino option for this pet.
The Lime Ardur is definitely the best.
No matter what you decide definitely go with the Azure Zenirix and good luck, dude!
