Lucas Sieuzac - He's given me one of my all time faves, Reflection Man, but I like almost everything he's had a hand in. He also did Jubilation 25 which is fantastic, and Wicken 3000 which is interesting and minimalistic. His style seems to be very modern, with an emphasis on synthetics injected into a natural framework. He likes to incorporate dualities (hot/cold, bright/dark, etc) into his compositions, too, which keeps them interesting to me over many wearings.
Daniel Visentin - Yep, I think Lyric Man is just that good. I don't know what else he's done, and I don't care (ok, well, I do care, I've just not been able to find anything else attributed to him!). I guess I'm one of the few who prefers Lyric Man to Woman. I find it so beautiful within a natural (as in nature-oriented, not natural ingredients) context - the dew collected from roses at sunrise.
Karine Vinchon - Her Memoir Man is a scent that was designed for me. It fits me in so many ways - it is very very brooding, almost stand-offish. Yet, there is a beauty and harmony at play. I've only smelled this and Opus III by her, which I also quite enjoy even if it's not really "me" (it's more of a mood scent, anyhow). Her style, as far as I can ascertain, involves scents that are quite thick in texture and body - the opposite of say Giacobetti (whom I also love).
I would have included Jean Paul Millet Lage who made one of my other all time favorite scents, Bois de Turquie, but he also messed with a lot of MPG's greatest scents (Route du Vetiver! Grr!) and so I felt I should give the third spot to Karine Vinchon whose work I've only enjoyed thus far.
For the most part, I don't find many perfumers of whom I love the majority of their works. I love a few of Duchaufour's creations (Al Oudh, Jub XXV) and like many more (Sienne L'Hiver, Paestum Rose, etc), but there is something in his style that often leaves me with a relative indifference to his scents. Daniel Maurel has done some really good work with Amouage, but I find his scents often too sweet. The Creeds have been entirely hit and miss with me. It seems this is the case with nearly everyone, thus why 2 of my top 3 are there simply for a specific scent they created!
I should include a few more honorable mentions: Olivia Giacobetti - honestly, I would have had her in my top 3 if only Memoir Man wasn't so perfect for me, thus necessitating the inclusion of Mrs. Vinchon. Navegar and Costes alone secure a top spot.
Isabelle Doyan - I've still SO many of her creations to sniff; almost all of the Annick Goutal house. I really loved her work for Les Nez though, and really like her style. She could move into the top 3 after I experience more of her work.
