Lord, where to start.....
If you love the whole Lutens sweet spice/stewed spice thing (which I do), then you can't go wrong with:
Chergui (smoky sweet spice with hay and vanilla drydown)
Fumerie Turque (smoky honey)
Un Bois Vanille (sweet woods)
Arabie (a whopper of stewed spices -- on me, cool weather only)
Mandarine Mandarin (the love child of Fleurs d'Oranger and Arabie)
If you like a little leather with your sweet, then:
Sarrasins (jasmine + lots of leather -- at least on me)
Daim Blond (apricot + suede + a hint of smoke)
Cuir Mauresque (leather + spice + leather + leather + leather) -- did I mention there was leather?
Muscs Koublai Khan is in a class all by itself -- it's a bit drier at the top and middle than other Lutens, but there's a fabulous waft of leather on me at about the 10 minute mark. The dry-down is softer, sweeter, and delicious. I don't know where people get the whole sweaty horse genitalia thing. It's wonderful.
Chene and Santal Blanc are two of the drier, less sweet Lutens offerings. Although Chene starts off with a boozy blast of something (rum?), that vanishes pretty quickly on me and goes straight into an amazingly realistic oak that softens slowly as the immortelle comes on. I find Santal Blanc challenging to wear on its own (very realistic newly-sharpened pencil shavings) but fabulous when layering. I often layer Santal Blanc underneath Carnal Flower or A La Nuit in the summer.
And, the ones that started it all for me:
Bois de Violette (lovely sweet violets with a shock of cumin and cedar -- this, along with Apres l'Ondee, is my favorite rainy-weather fragrance)
Feminite du Bois (Bois de Violette only spicier but less cumin and some plum)
Can anyone say "Lutens Slave/Addict/Slut?"
