I love their eaux, especially Acqua di Colonia and Acqua di Sicilia. But for me, Melograno is the star of the line.
If one is looking for an uncompromising leather, Peau d'Espagne should be checked out. Many love Nostalgia too, personally I find the drydown to be lacking. Zagara is one of the juiciest and most natural nerolis around. Tabacco Toscano is very nice soft and smooth vanilla & tobacco.
Oh, and one often overlooked one is Vaniglia. Non-sweet and light, even a tad smoky vanilla. Very, very nice and simple - and outside the Italian taxfree stores also very expensive for what it is. This applies also to the EdC's.
Sorry for the disorderly and superficial answer. This is what happens when I just start typing with my phone while drinking my Sunday morning coffee.
