I personally prefer L'ombre Fauve but think that both could fit in one wardrobe. (though I'd replace MR with MKK)
L'ombre Fauve is a complex sexy animalic and ambery blend of musks, woods, incense, and patchouli that feels like wearing a second-skin from a cougar's fur coat, making you feel like the predator. On the other hand, Musc Ravaguer is an animalic vanilla and cinnamon that is on the sweeter side with a surprising absence of musk. (initially at least) MR would be the prey in this case. It's good, but there are better options out there.
