I do think normals are underrated. the contrasting markings are very pretty and I wouldnt hesitate to own one if i were taking in more balls. But to answer the question, Pied, hands down. Black Eyed Lucy next. All of the stripes I ahve seen have been good looking too. We have a cinnamon and he a nice looking snake but we bought him because he was just so cool and collected witht he family handling him. I have enjoyed him more than I expected to. Some of the pastels are nice but they can vary wildly. Picked up a baby pastel for my oldest daughter and he is nice looking.
Here is Wedjet, the cinnamon, doing what balls do...
And here is Dufus (my temporary name for him) being camera shy...
