My wife enjoys both. Lucky me. Just one comment, is there a difference for a man to cum on a woman's face and a man to get lots of pussy juice on his lips and face? I don't see how the former is any more demeaning than the latter. Of course, people have preferences and no-one should be expected to enjoy it (I know it stings if it goes in the eye) but usuing the word "demaning" is not helpful.
I prefer mouth because you never know where it's gonna go when he chooses the face, I don't like it in my eyes or my hair.
