In short, I dislike them both but to unequal degrees.
I feel uncomfortable and dislike wearing DHI due to its heavy use of iris, though have no issues with its performance aspects as it does just fine in both longevity and projection. Eau Sauvage Parfum is an insult to the legendary name it ill-advisedly uses (as it smells nothing like the classic), is cloying to the extreme and is just *way* too strong, projection and longevity-wise both. Even one spray for me was too many and it would have been a definite scrubber if it would have actually scrubbed off.
The ESP is the better performing, but I easily prefer DHI of the two.
