Ball Python cause In my experience less people are afraid of snakes than they are scorpions. If someone doesnt like snakes don't take it out or put the snake in a tub instead of an aquarium. I like both but I would say a ball python. Plus Its great when people learn that ball pythons make great pets and it would be an awesome learning experience. It all comes down to would more people warm up to a snake or a creepy crawly.
