I think there is not a correct or incorrect answer.
I think each women can have a different approach and it can be the better option.
Morphology of her body, kind of hair, ... that kind of characteristics are wich composed a better option; and there is just one person who knows all those caracteristics better for getting the better result: each women.
So each women should decide how she feels better, how she thinks looks like better,...
Perhaps industry (you know much more than us about that) just evaluate statistics about how is supposed mens like more this topic and they force models to adopt that supposed likes.
In my point of view the question is like think about what kind of breast is better; each women is different and as example i like proporcionality as a sign of beauty so...i think there is no just one correct answer.
Have a great day!
