Great thread. I'm happy and able to vote for the ones on the list that I think rate top of the classics status. From the ones listed it's easy to pick great ones, and it's also hard to not pick three-quarters of the list. I voted for five or six myself, but could have voted for twice that many.
I like Egoiste like everyone does, but I don't find it interesting enough to be a top of the classics choice for me. Smells really great for sure, but it isn't really involved--which is what usually makes a classic for me.
