I'm going to have to disagree with enso. If the snake doesn't appeal to you, do NOT get it. You will only end up with a snake that you don't really have an enthusiasm for, potentially leading to its future sale or even lack of care.
All of the above listed can make great starter snakes (which I am assuming this is?). I say do your research on each one and see which one appeals to you the most. Asking us a question like that is like asking US what YOU want to eat for dinner
Everyone will only be giving their personal preferences for what they like, not what you like
Good luck with your decision
