Hum.. I'm not that into perfume world so I can't give you the exact name of the different scents in it but I have both Ed Hardy perfume and:
They are very different, the pink one is sweeter and... warmer ? as the Love&Luck is more.. fresh and citrus woody? the staying power of both is about the same but you do have to wear them to know as the Love and Luck one smell 2 different things from the bottle to skin (at least for me)
And I like both a lot. They are just different so... (You can find samples on ebay for 1$ or 2$)
