Many good questions generate some degree of opinion based on expert experience, but answers to this question will tend to be almost entirely based on opinions, rather than facts, references, or specific expertise.If this question can be reworded to fit the rules in the help center, please edit the question.

Here's a more general question that may have some bearing on it: Are similar smells usually based on similar chemicals? –  Oreotrephes Dec 20 '13 at 20:58
