I'm a little surprised nobody mentioned Musgo Real Classic. By far my favorite AS. Superb scent, and it leaves the face moisturized, almost like a lotion. Great stuff.
I don't use it that frequently but I've always got a bottle of Royal Coppenhagen AS around. My wife (then girlfriend) first bought it for me back in the 80s and it stuck.
On a more recent note, Proraso Green is my most frequently used. I just wish it had a little more staying power.
I don't know if I contributed to this thread or not:
AV Ice Blue
Master Champagne
Old Spice (or some version)
Pinaud Classic Vanilla
Avon Oland, Windjammer and Leather
Gillette Cool Wave
Nivea Balm
I could probably live happily with those for a long time.
