Well, I have issues with Aventus...can barely smell it, but last wearing it was getting through to me more. It gets noticed on me big time though. Amazing in that regard.
SMW is to my nose also a bit of an elusive scent, but it too has a strong following.
I'd go with Aventus. Or, if you like them both, get a bottle of each instead of a flacon. Is there is a reason you must get a flacon? The price per ml get you down otherwise?
