Photozone figures show the f4 IS turing in a more even performance in the corners stopped down, with better corner figures at f5.6 -f8 at the 3 tested focal lengths.  In my experience, the 2.8 still edges out at 24mm, but not rest of the way at least in the corners.  In ballance, I have found the f4 to be a better landscape lens.

the 2.8 II, has good corners at all focal lengths wide open.  however, esp at 50, it never becomes tack sharp.  both lenses have very good center sharpness wide open.  It may be that the 2.8 does better, but both are very sharp in the center.

To me, the center and off center sharpness maters wide open, and corners matter stopped down. the f4IS, does at least as good of a job, and it has less distortion at 24 to boot.  However, it is still only an f4 lens.
