Heritage for me, better yet in the EdP form but still with the EdT over Egoiste.
Egoiste is excellent indeed but as with most Chanel's, it does not perform well on my skin. I cannot much get longevity or any projection from it after the first 1/2 hour or so. I have a bottle from the early 2000's and it was the same way back when it was introduced. This is my third bottle and I still like it and wish to have it in the accumulation. And BTW, to my nose, it has definitely been reformulated but so has Heritage.
