Way too many to list! I would like to second Diptyque and Frederic Malle. Also Basala, Serge Lutens (both bells and exports which I find quite elegant), and Molinard Homme. Finally, Nicole Farhi Homme which is a beautiful and quite unique piece of modern sculpture.
I'm surprised Coriolan has only received one vote so far! It's an absolute gem of a design. When it relaunches as Ame D'Un Hero it will be in a more traditional Guerlain bottle, which is attractive but not quite as innovative.
I would also concur with Terre D'Hermes and of course Guerlain's Vetiver which is a beautiful bottle.
Dior Homme is a very pleasing simple design - I also like Gucci Envy too.
