Since it appears to be a contrast thing, I would expect that a lens that manages to keep more contrast will have more fringing. I'm not saying that's a good thing but the lens capable of transmitting the higher contrast will appear sharper with certain subjects while the opposite will give less fringing in hight contrast situations. Now my optical analysis could be all wet. I only have anecdotal data...
