Great review Indie.
Yes I must agree with your comment, 'My only reservation is that the sweet coumarin base seems to rise up a little too quickly to steal the show from the strange and deadly topnotes' - I feel this way about most Gaultier fragrances. However the neroli/white flower/milk reference is quite true and honestly I 'see white' when I smell FdM too.
Reading most of the blogosphere's year end lists, FdM appears on a few of them also - so it seems you're not the only one who is enjoying this new scent.
Honestly I can't imagine owning a bottle of FdM because I find it a tad too similar to my cherished L'Occitane Neroli (the discontinued one). But if anyone on the boards is looking for a male white floral scent that's unique and different I would wholeheartedly point them in the direction of FdM.
