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
Hamilton Beach Duo brings a small bowl and snap assembly. Cuisinart Custom 14 fits cooks who want one large bowl and fixed 4 mm slicing.
Before you buy
Hamilton Beach gets a small-batch option from the extra four-cup bowl, and its largest nominal capacity stays the same.
Where this comes from
Only 70585 lists a separate four-cup nested bowl, though both main bowls are 14 cups.
The catch
Cuts from the slicing and shredding disc are fixed, with no thickness adjustment.
The catch
Slicing happens at one fixed 4 mm thickness, set by the supplied disc.

A small bowl and snap assembly are what Hamilton Beach Duo adds. Cooks who want one large bowl and fixed 4 mm slicing should look at Cuisinart Custom 14.
A traditional large-bowl processor, or two bowl sizes with snap assembly
Which one fits
Along with the equally sized main bowl, Duo supplies a four-cup insert.
The stated 4 mm disc and a separate medium shredding disc come with Custom 14.
Adjustable slicing thickness is not offered by either supplied disc system.
Cooks who find traditional bowl and lid alignment awkward may care that Duo snaps together.
In practice
Hamilton Beach gets a small-batch option from the extra four-cup bowl, and its largest nominal capacity stays the same.
Only 70585 lists a separate four-cup nested bowl, though both main bowls are 14 cups.
Although Custom 14 lists 220 watts more input power, that does not quantify how either machine chops the same onion.
720 W - 500 W = 220 W, and the cited specifications include no matched food-processing test.
Custom 14 is an obvious match if a 4 mm cut serves you. Cooks who need selectable thin and thick slices should widen the shortlist.
Hamilton Beach specifies a fixed reversible slicing and shredding disc, and Cuisinart specifies a fixed 4 mm slicing disc.

Hamilton Beach, 70585
Nested 14-cup and four-cup bowls, separate chopping blades and a dough blade come with this snap-together processor.

Cuisinart, DFP-14BCNY
Large bowl, strong chopping, steady disc work and simple paddle controls make this a proven design.

Decision guide
Choose Hamilton Beach Duo for a small bowl and snap assembly. Choose Cuisinart Custom 14 if you want one large bowl and fixed 4 mm slicing.
Both main bowls are 14 cups, so Duo does not raise your largest nominal batch. What it adds is a four-cup nested bowl for an onion, herbs or a sauce that would otherwise take up the large Cuisinart bowl.
Duo snaps together and its main bowl is sealed with a pour spout. The Custom 14 uses its traditional lid and pusher arrangement. Handling differences like these come back at every setup and cleanup, unlike a motor figure you read once at purchase.
Custom 14 comes with a fixed 4 mm slice and a medium shred. Duo comes with a reversible slice/shred disc whose cuts are fixed. Neither allows continuous slice-thickness adjustment, and neither includes a true dicing grid.
