For me it's easily Olivier Durbano's Jade. It's ridiculous. The first time I ever wore it I applied it and then got in the car to go somewhere. It was so potent in the car that it was like it made the air thick. I kind of got a headache and even started sweating because I was having a hard time breathing. Then, the sweating increased the potency even more and I thought I was going to pass-out. Crazy. Needless to say, my decant has nary been touched again.
