Hey fluke, welcome.
Of the three you got, A*men definately gets the most airtime here at Basenotes. Some swear by it (for its originality, its delicious chocolateness, how strongly it broadcasts its smell). Others cant stand it (for largely the same reasons). You'll have to leave it up to your nose and skin, but A*men is def. an original fragrance which engenders much heated discussion amongst those of us who spend hours talking about smelly things. While lots of Bnoters will insist upon the principle that you can wear whatever you like in whatever weather, I think you would quickly regret wearing A*men on a hot and humid day. In the winter, though, it is SUCH a comforting scent.
212 is indeed a fresh fragrance, aka the "me-too acquatics" which is a genre of scents often derided on these boards, Basically, thats us being reactionary: these fresh acquatic scents are so popular outside of Basenotes that fragrance afficionados simply have to look down upon what we see as an "easy way out, path of least resistance, individulity-less" style of cologne. That said, on a blistering hot day, there is nothing more refreshing than a well-made acquatic, and 212 on ice is one of the better ones, IMO.
As for d'Orange Verte, I am not familair with it mayself, but you can check this out: http://www.basenotes.net/ID26120490.html
