Best guerlain perfume?

Crossed paths with a woman today and I noticed I really liked her perfume so I asked her what it was, it came off as kind of gate-keepy, didn’t get the name of it but I did get the brand of it. Was wondering what your favorite was from this brand so I can try it out :)

Convo went something like this

Me: I really like your fragrance, what are you wearing?

Her: oh its from France

Me: that’s so cool what is the name of it?

Her: it’s Guerlain

And then she walked away:(
