Absolutely Yes! Not only should these two classics be different, but they certainly are. Habit Rouge is altogether sweeter than Heritage, and for that reason I principally wear HR in cool/cold weather, while I wear Heritage all year long. Heritage is imho the more formal of the two scents, and is a little more appropriate for an office setting, or to be worn with a sharp suit. I am neither scent's biggest fan, but am glad to have both in my wardrobe.
