Best design bottles: Mona di Orio (great looks and very functional as well).
Worst design bottles: Bulgari (I love the look of many of them, but storage/use is difficult due to their odd shaped design choices).
Best sprayer: 212 Men by Carolina Hererra. (I can't stand the juice, but the sprayer is easily the best I have ever come across).
Worst sprayer: Due to the bottle design issues mentioned above, Bulgari fragrances are difficult to target and spray properly.
Best packaging quality: Mona di Orio, By Kilian, O'driù (all three provide top-notch packaging).
Worst packaging quality: Creed (like the juice inside, extremely inconsistent and unacceptable quality).
