M7, if you love smelling woody and aromatic. it's like hugging a lug of wood. smells absolutely gorgeous towards basenotes.
Musc Raveguer, if you like spicy scents with a sweet, vanilla base. smells very aromatic towards openign with a hint of gourmand...and subtle, but suave towards base.
Both are poles apart in the genre they represent. M7 would be a bit edgier for year round use as opposed to Musc R.
