Even though the first one is prettier now, I would probably pick the second because it has more genes. That is of course unless the first is a two gene animal, like a banana cinnamon. In that case you should decide which genes you have more interest in working with. The thing you have to remember about bananas is that they do not age well and the first one will loose most of its purple coloring, where as the second will most likely look more similar into adulthood.
