I have a ball python and my son has a rosy boa. I think the rosy boa requires a lot less management in terms of his habitat, because we live in the desert - humidity is not an issue for rosy, nor for us. The rosy boa is very docile, slow moving (more active than my BP though), and is a snake my son can care for completely on his own under my watchful eye. My heart belongs to my BP, Tiki, but the rosy boa is easier to care for, in my opinion.
