The main reasons to use the f:2 version are (of course) the maximum aperture and it's attendant shallow dof, and the close range correction. High speed films have improved greatly, so fast lenses aren't as neccesary as they once were. The other aspects may be important to you though.
As a sort of parallel, I once had the 35/2.8 and the 35/2, both pre-ai. I kept the f:2 because it had more even illumination.
well I really wanted the extra stop and a half of lens speed, and thought the CRC would make for better performance throughout the whole focusing range. I am now considering going a cheaper route and getting a 35/2 for low light situations and holding on to the 28/3.5.
