The catch
KitchenAid 9 Cup Food Processor
You cannot fine-tune thickness, since the slicing disc is fixed.
Side by side
For average households, KFP0921CU is the more balanced choice, and it comes with a whisk. Large batches, and cooks who make frequent use of the ExactSlice lever, are the territory of KFP1318CU.

A 13-cup model made for bigger produce and adjustable slices takes on a multi-purpose nine-cup set.
This one comes down to bowl and slicing first, then to the limits of your own setup.
Day to day
Say you slice potatoes for one dish and thinner vegetables for another. KFP1318's external thickness lever changes the slice without swapping out a fixed-thickness disc. KFP0921 uses a fixed disc, which is fine if that cut matches your menu. Go with the thirteen-cup model if you change thickness often, once you have checked how your ingredients fit. The larger feed tube does not spare you from preparing every oversized ingredient.
The exact-model evidence already on record shows external ExactSlice control and a three-in-one feed tube on one side, and a fixed disc with a two-in-one tube on the other. Nothing is inferred about cutting speed or perfectly uniform slices.
If you expect to whisk as well as chop, note that KFP0921 comes with a whisk and a refrigerator lid, while the selected KFP1318 package puts its emphasis on slicing tools and a storage caddy. The larger processor is not a straight upgrade for every supplied task. Pick the nine-cup set if the whisk is a tool you will really use, or the thirteen-cup set for adjustable slicing and its broader working bowl.
What is being compared is the packages, and nobody is claiming that larger motors cannot whisk. The selected thirteen-cup offer does not list the nine-cup whisk, so you need to check compatibility or an optional replacement on your own.
