Ehm... sorry to be a bit pedantic, but the distinction between the two has no effect on your argument here. Either way there are ten times as many environments in which stuff happens.
Also, as b3lvedere's comment points out elsewhere, you really shouldn't trust gut instincts when it comes to reasoning about infinities. Unless you're a mathematician specialized in the subject, you're pretty much guaranteed to be wrong about them.
(having said that, I'm also more inclined to believe that there's plenty of life out there. I'm not as hopeful about complex life-forms escaping planets though)
