I think these last sets show how strong the Leica is, and start to show the weaknesses of the Zeiss. The purple fringing is much stronger in the Zeiss shots, and the Leica shots give a better impression of sharpness. I am not sure that you are going to see night and day differences, but clearly more money give better performance in this case.
Before deciding, you should also go out and shoot what you normally shoot, and make sure that you like the look of the lens you keep.
