Sorry, I voted for Blender. Even though it's interface is not very good, it is still an extremely competent program AND there are very good documentation.
He he, no hard feelings. If you see my previous reply you'll see I've played with the idea myself ^^ Often times when we've been working on some overall project improvements, we've looked to Blender as the de-facto "open source software project" template. They're far from perfect, not that its commercial counterparts are, but they do a lot of things really well.
In my line of thinking though, jMonkeyEngine is the underdog-extreme in this contest, and we have a lot more to gain from this than Blender, so I'll honestly admit I won't let my pride get in the way of a couple sympathy votes
