For me is the opposite.
I really love the thickness and quality of hair. For me, with a really healthy mane with perfect genetics waist or butt length is the limit... because is very long to be long hair, it's affordable to care and is the limit of the comfortable to wear. More length is, old thinner open ends and uncomfortable to wear. Mid back or little longer is just perfect... but healthy, thick, luscious and with movement, longer manes has worst movement than shorter ones. I even don't consider extremely long hair as a good aesthetics.
I like shorter manes too... but from boobs to waist, is where perfection is.
Examples of perfect hair IMHO:
Alex Arriaga, of course:

And My fascinating Hair (Anna Lena)... she's probably the girl with longer hair I consider perfect for my fetish, 'cause she has long hair, but healthy from head to ends, and extremely thick and with a fantastic colour.

And in the other extreme, Karina Berezhnaya is the shorter hair I like... it's a little short, but very thick and with a really nice texture and movement.
For me the points are: 1 Thickness, 2 health, 3 nice colour (don't matter what) and 4 sexy movement. Of course that's me, and my opinion and my tastes. If you prefer hair long until the floor well, there is no acounting for tastes and I respect your opinion.
