I agree completely. If you have done a proper AF lens calibration, the FA43/1.9 will amaze you with its center sharpness at f1.9. It is definitely sharper wide open than the FA31/1.8.
I tried multiple copies of the DA*55/1.4, which I wanted to use for portraits, but could not find one that could focus accurately and consistently. However, even when it did manage to hit the correct focus point, I got the feeling that it was very soft and low contrast wide open. It was better at f2 but still not as sharp as the FA 43.
The real question regarding the FA43 is whether it is a focal length that you want to use for portraits. Given that I have taken many great portraits with the FA31, I see no reason why the FA43 should not serve that purpose very nicely. Its focal length is equivalent to 65mm in 35mm format, which is not quite the classic 75-85mm for portraiture, but close enough for my work. I also have the FA77 for when I want tighter shots of faces, but most of the time the 43 should be great. Some people say that it is too sharp for portraits, but I do not subscribe to that theory.
