It depends on what you mean by "better." The DA40 is at least as sharp, but it also exhibits somewhat stronger, less subtle contrast. Also, look at the flowers in the background. They are much more pleasingly blurred in the FA43 shot, and I cannot believe that that is entirely attributable to an additional 3mm focal length. Rather, this is the vaunted bokeh that is characteristic of the FA Limiteds. Indeed, the FA31 has softer bokeh, and it is 9mm shorter than the DA40.
That said, I really don't think that anyone should draw firm conclusions based on these samples. Thanks to the OP for doing the work.
