What cologne should i purchase?

Why would you want to get any of them? If $150.00 you have to spend you obviously have the budget for some GREAT cologne, so to me it sounds like you're either looking to be the big man on the block with the most expensive cologne or are trying to impress somebody. For that much money you should spend it on a Creed or something unique, not an upgraded offering from a perfume house that isn't even a major perfume house. Davidoff, Kenneth Cole and Tom Ford are all clothing houses anyway, not perfume houses. Go with Creed or Cartier, Hermes, Guerlain, Givenchy, Yves St-Laurent, or Boucheron. Kenneth Cole is good and so is Tom Ford. I have heard only good things about Grey Vetiver, I have not heard much about Vintage Black but I have heard it been mentioned once or twice. I wouldn't buy Davidoff if they gave me a million dollars for a product endorsement ( I CAN'T STAND COOL WATER. TACKY, SIMPLY TACKY ).
