I guess it's a matter of taste. I prefer the long straight curve too because it lets me burn in the highlights and end up with higher highlight contrast than with a film with s-shaped curve. But you have to do this and this means more work in the darkroom. The shoulder can be replicated (sort of) by preflashing the paper.
The s-shape is more convenient because shadows and lights need less (or even no) additional work. But the contrast in the highlights is lost.

I think the main question is how important is shadow and highlight contrast for this particular photo.
