All right then, I'll pull for Jicky. MdM just didn't have enough oomph for me and although it smells remarkably similar to Jicky (albeit different), Jicky gets a leg all the way over the horse. I love the extra attitude that Jicky has, a serious bit of posh with enough skank and frivolity to make it fun. MdM is too timid for that kind of wearing.
The answer to the OP's question involves a complex multi layered matrix. Thankfully, now that many of the scientists from NASA are unemployed perhaps we can find one to help us answer.
In any case, there is no one Jicky just as there is no one Mouchoir de Monsieur. There are differences with the reformulations, most notable with the different bottle styles - though there are intra-bottling reformulations best denoted by the date code - as well as differences with the strength formulations. Jicky EdP is far different from Jicky Extrait which in no way compares to Jicky EdC; so on and so forth....
To simplify, it depends on what you want from Jicky or MdM. If you want less civet Jicky EdT would be best, more civet go to the EdP. Though EdP wears closer to the skin than the EdT, and Extrait closer still. Jicky EdT is the easiest to find and probably the safest to buy, especially if you're not OCD about which formulation you get. The one in the stores now still smells good....and really, isn't that all that matters?
Ungaro II would also be a good choice to try if you're looking for a scent that is a freak in the sheets and a lady in the streets.
An EXCELLENT follow up post, Aaron. I confess I was waiting for you to chime in since I've noticed you wear more Guerlain than most folks on these boards. Your comment about "depends on what you want" is spot on, because that's the core thing about Guerlain. The best example for that to me is in Habit Rouge, which is citrusy in the EdC, less so in the EdT (but more leathery [and still citrusy]), and even more butch in the EdP and parfum. Yet the construction is still always and unmistakably Habit Rouge. And of course, I will wear each one depending on "what I want" from Habit Rouge.
"A freak in the sheets and a lady in the streets."
Yes, please, that's my kind of woman, er, I mean, fragrance.
Putting Ungaro II on the list.
