I would take one in a heartbeat. But, it would have to be male. I do not have the space for a Dumerils boa.
From an outsiders point of view (no boas in my collection), I think it's very likely the morph aspect. With boas, you can walk up to someone and have a discussion about genetics and what your plans are for any breeding in the future, etc. With a Dumerils boa, you walk up to someone else with one and it's like: "That's awesome. I have one too." That little bit of variance in discussion by learning about genetics behind the snake make it interesting. Almost like it's a mini competition, if that makes sense? Haha. "I have an Albino." "Ohh nice. I've got a stunning Jungle at home!"
Personally, I'd take either one. I'd probably prefer a Dumeril. But that's because I've met so many amazing ones, and their strength is just so cool.
To each their own, I suppose!
