End/Beginning was my favorite from series 2. Distinctive incense-heavy scent. Nicoll No. 17, also from series 2, is a gorgeous dry, herbal-sweet scent focused on fennel that sadly fades to an indistinct base far too quickly.
From series 1 (why are these still not in the database?), I remember liking #2, without remembering why.
But my favorite is the one saddled with the worst name of the bunch and with a ridiculous over-the-top homoerotic brief from designer Jeremy Scott. Series 1 #5, Illicit Sex, is (when all is said and done) an intriguing peppery, aldehydic floral, unlike anything else I own. Give it a try!
