I had a thread on the exact same thing earlier: http://community.basenotes.net/showthread.php?t=216288
I ended up going for the Un Crime Exotique. 5 o'Clock au Gingembre is more "ginger," while Un Crime Exotique is more like gingerbread/baked goods. On some days when my nose is tired, the 5 o'clock smells extremely transparent.
If you want a 100ml bottle, be sure to shop at "The Perfume Shoppe." (better value than LuckyScent)
