I've owned and/or tried all of them, except Mojo, and this whole ordeal has been confusing, even to me.
I think we've got everything straightened out with this thread now, though.
I've got a bottle of Gendarme 20 available for sale right now, btw. I find it to be the same as the original, with the best lavender note I've ever smelled. I prefer it to the spicier Creed RSL. I don't need "20" and the original, though, I don't think.
