I haven't smelled Unbound, but 360 Red is a very good clone of ADG, that lasts a bit longer. The main difference is that 360 Red is a bit fruitier, while ADG has more floral/oceanic notes.
Also, if you like this smell, give Paris Hilton Just Me for Men a sample as well. It was created by the same perfumer that did 360 Red, and is very similar (but I think a bit better & more aquatic).
