The catch
Hamilton Beach Stack and Snap Duo 14 Cup
Cuts from the slicing and shredding disc are fixed, with no thickness adjustment.
Side by side
With two bowls, Hamilton Beach Duo handles large and small batches. Changing slice thickness during vegetable prep is easier on KitchenAid 13 Cup.
Before you buy
Duo's main bowl has less than 8% more nominal space, so adjustable slicing can easily matter more than capacity here.
Where this comes from
(14 cups - 13 cups) / 13 cups × 100 gives 7.7%.
The catch
Cuts from the slicing and shredding disc are fixed, with no thickness adjustment.
The catch

Whatever their slicing features, neither standard accessory set has a true dicing grid.
In practice
Duo's main bowl has less than 8% more nominal space, so adjustable slicing can easily matter more than capacity here.
(14 cups - 13 cups) / 13 cups × 100 gives 7.7%.
For a small dressing next to a family-size slaw, the Duo four-cup insert makes it the more flexible choice.
70585 comes with a four-cup nested bowl and matching S blade, whereas KFP1318 lists a single 13-cup work bowl.
When one prep session needs both thin and thick cuts, KitchenAid earns its place, since its lever changes that output directly.
KFP1318 has ExactSlice, which adjusts from outside, and 70585 lists a fixed slicing and shredding disc.

Decision guide
Choose Hamilton Beach Duo to cover large and small batches with two bowls. Choose KitchenAid 13 Cup if you want slice thickness to be easier to change during vegetable prep.
An external ExactSlice lever on the KitchenAid helps when potatoes and cucumbers call for different thicknesses. Hamilton Beach uses a fixed slice/shred disc, so its larger bowl does not buy you the same cut control.
With its 14-cup and four-cup bowls, one base handles bulk prep and a small sauce. KitchenAid has a 13-cup bowl, and its main emphasis is a wide feed system and organized tools.
An in-bowl storage caddy comes with KitchenAid. Duo nests its smaller bowl inside the larger one, yet it still leaves separate matching blades and a dough blade to keep track of. Think about where those sharp parts will live between uses.
