Welcome to basenotes!
Guerlain Vetiver, I wouldn't really recommend you trade this off. This one is a masterpiece. Keep it, keep trying. Maybe it will grow on you. Maybe you did over spray. Or maybe just doesn't work on your skin with the current weather from where you are right now. Try it on a different season. Guerlain Vetiver is very versatile anyway IMO.
I can't really say much about the other 2 for I have never smelled them. Although I have read a lot of good stuff about Azzaro Ph. In fact, it's even one of Turin's top 10 masculines. Should I blind buy this one? Anyone?
