The one with 20 samples for like $40. Nice to be able to try each one multiple times over many months and really decide which ones you like.
Some of my favorites: Like This, 500 Years, Clean Suede, Hermann à mes côtés me paraissait une ombre, Archives 69.
Most of the ones I liked were warmer scents; archives 69 was sweet and floral, but the rest had ginger, gasoline, cinnamon notes.
Overall a lot of fun to go through them all even the ones I really didn't like.
