I simply don't understand the praise that Terre d'Hermès receives here. It is an unequivocally good fragrance—indeed, it is much better than a vast majority of new releases but that means very little. It is a bit of a big fish in a small pond. When compared to other department store fragrances, Terre d'Hermès is a breath of fresh air; however, once you leave the department store, Terre d'Hermès doesn't seem quite so interesting.
Terre d'Hermès is a nice scent—something I would feel comfortable wearing to the office; it's safe, dependable, versatile, and it will absolutely not offend anyone and because of this I will never wear this fragrance. Where's the fun in wearing neutral colors and going completely unnoticed?
In any case, Midnight In Paris is a beautiful, interesting, unconventional fragrance. I would purchase it but I already own Black by Bulgari and I prefer the more in-your-face rubber note to the more subdued leathery facets of Midnight In Paris. And as others have already mentioned, go with the EDP (The EDT has more citrus on top and feels thinner throughout; I feel that the difference is noticeable beyond longevity).
