Childrens are still beautiful, but I get what you are saying. I find that the presonality of my spottie makes her the most pretty, gorgeous, amazing girl that I have ever loved. My jungle is pretty and a stunner to look at but you never quite have the connection with other pythons as you do with an anterasia IMO.
My top 3 answers for you would be:
1. Jungle, they are stunners and will calm down with handling.
2.Woma, they are beautiful and calm and don't grow overly large
3. Darwin, normal or albino, you still have a gorgeous snake!
That's what I would go for but idk, you might have something different in mind?
