This is a tough one. Although height is important for dominance, ultimately a tall person is just a stretched out version of the same person and thus not aesthetically superior. Would a painting be nicer to look at if it were vertically larger?
If I'm going to be an incel anyway (unlikely though if 6'6) I would rather be in the friend zone of a foid who thought I was cute like a puppy rather than be in the empathic friend zone of a foid who had to fight back her repulsion towards my face.
When you die, people are going to display a photo of your face; possibly of your prime. You cannot show a photo of someone's height because it's a number.
I like being buff and everything but an accident or disease could put me out of the iron game forever. In my old age I will also not be physically dominant but I could still have a beautiful face if I protect it from the sun. So I would say that face is more important depending on your aspirations.
