What's your favorite astromon?

Which of these creatures do you love the most, and why? It can be based on viability, or just how nice it looks.

Personally I'm torn between two. Evo. 3 L Gemini and Evo. 1 Water Valkyrie. Light Gemini, in my opinion, is the cutest Astromon this game's released to date. Though Water Valkyrie's design is so clean to me, and her little wings makes her extremely adorable. She was one of the first 5*s I wanted, and pulled her in my first Hero Festival.
