I voted Gris Clair because it smells fantastic and is ... in my opinion ... the most versatile one there. *Fumerie Turque is fantastic, but I think much better for cooler weather. *BdP should be a staple in everyone's wardrobe, but much better suited for formal or evening. *MKK is plain scary to me ... and Musc Ravageur I just didn't like.
And to top it off ... although many around here adore it, I have a deep hatred for Egoiste.
