The person you are purchasing for is in for a treat-I 'm a total Creed fan!
here are some of my insights for you-hope they are helpful. I do not find any similarities to 1 and 2, at all! FdF is , to me, an over the top, ebullient blend of tuberose and roses and osthmansus (sweet apricot). 2000 Fleurs smells to me of lilacs, which are not a personal favorite of mine. I have not smelled Fleurs de Bulgarie, so cannot comment on it. Fleurs de Tea is a linear rose, extremely fresh smelling, with a green tea not that i adore. At first I found it a bit disconcerting that it never changes, never morphs into anything else but now I really enjoy it. Tuberose Indiana is a tuberose and ambergris blend. I adore it, but cannot smell the honeysuckle note you refer to. Perhaps my nose is not as good as yours! I find it a really swoonworthy perfume. Have you tried Irisia? I am such a fan of Irisia I wish it had its own fragrance board. What pther sorts of fumes does your friend care for? Let us know what you choose!
