I'm not sure what the composition of Arcus is, but today (as I finished my sample vial) it struck me how similar the top notes smelled to Bond No. 9 Wall Street... it's gotta be the cucumber, it smelled exactly like extremely fresh, wet cucumber when first sprayed on. Very refreshing.
While neither is bad, neither is great either. On the whole, I'd give the edge to Wall Street in a head-to-head comparison... it has better staying power and is more marine-fresh (which I like). Four hours into the Arcus and it's barely detectable.
