I’m not disagreeing with you entirely. If you took the woman in the picture and put her next to a woman with the same quality hair but a foot or two longer, I guarantee 100% of us on this forum would choose the latter.
But in my experience, in reality this best of both worlds is hard to find. My first partner had hair down to her thighs, and while it looked incredibly sexy in photos, it was very thin and would tangle easily and tbh not super satisfying to play with in hindsight.
My most recent partner had hair to just above her waist that was extremely thick and soft and playing with it was euphoric!
I used to think long > short no matter what, but after experiencing different types of hair whipped across my body and wrapped around my cock, I would take quality > length any day.
^just my two cents
