The catch
Nutribullet Triple Prep System
Another large vessel to store comes with a separate work bowl.
Side by side
A separate processor bowl and two personal cups point to Nutribullet Triple Prep if they fit your cooking routine. A dedicated 18-ounce tamper bowl and an extra grating disc point to Ninja SS401. Slicing and shredding come with both, but Triple Prep keeps its processor work apart from the blending pitcher, whereas SS401 uses the large pitcher for both.
Before you buy
With Triple Prep, a prepared mixture can remain in the pitcher while the separate processor is fitted to the base. SS401 uses the same pitcher for blending and disc processing, so switching between those tasks may mean emptying it first.
Where this comes from
SS401's processing feed-chute lid fits its blending pitcher, while Triple Prep has one blending pitcher and one separate work bowl. Neither base operates two vessels simultaneously.
The catch
Another large vessel to store comes with a separate work bowl.
The catch
The same large pitcher serves both blending and disc processing.

Which one fits
SS401 shares that pitcher, while Triple Prep's separate work bowl can be fitted without emptying it.
SS401 includes one travel cup and a different small bowl, while Triple Prep includes two cups.
In this pair, that 18-ounce bowl comes only with SS401.
The feed-chute hardware and reversible slice/shred disc come with both.
Beyond its reversible slicing/shredding disc, SS401 lists a grating disc.
In practice
With Triple Prep, a prepared mixture can remain in the pitcher while the separate processor is fitted to the base. SS401 uses the same pitcher for blending and disc processing, so switching between those tasks may mean emptying it first.
SS401's processing feed-chute lid fits its blending pitcher, while Triple Prep has one blending pitcher and one separate work bowl. Neither base operates two vessels simultaneously.
SS401 has one 24-ounce cup, compared with the 32-ounce cup and 24-ounce cup that Triple Prep supplies. On Triple Prep, a second personal-drink user has an included vessel, subject to each cup's fill markings.
One additional personal vessel is what two supplied personal cups versus one comes to. The 18-ounce SS401 bowl is a different container with a storage lid.
SS401 supplies an 18-ounce bowl with an integrated tamper, and Triple Prep includes a hand tamper for its pitcher. Pick SS401 if the dedicated small thick-blend container is important, and do not assume Triple Prep has no tamper at all.
Ninja lists an 18-ounce XL Smoothie Bowl Maker with a built-in tamper, and the Nutribullet guide lists a pitcher tamper.

Nutribullet, NBKS50100
A 64-ounce pitcher, personal cups and a seven-cup processor, complete with a reversible slicing and shredding disc, all run off a single base.

Ninja, SS401
Made for thick blends, it has a powered bowl maker, an extraction cup and processor hardware next to the large pitcher.
Spec by spec
| Spec | Nutribullet Triple Prep System | Ninja Foodi Power Blender Ultimate System | In practice |
|---|---|---|---|
| Large blending vessel | 64-ounce pitcher | 72-ounce pitcher | Each recipe must respect its marked fill limit, since these are nominal vessel labels. |
| Processor arrangement | Separate 7-cup work bowl | Processing lid and discs on the main pitcher | While tasks change on the base, Triple Prep can leave one vessel's contents in place. |
| Personal cups | 32 ounces and 24 ounces | One 24-ounce cup | Two personal vessels in different sizes come with Triple Prep. |
| Small tamper bowl | None included | 18-ounce bowl with built-in tamper | A dedicated small vessel for thick spoonable blends comes with SS401. |
| Disc tools | Reversible slice/shred disc | Reversible slice/shred disc plus grating disc | SS401 adds a separately listed grating tool, and both slice and shred. |
| Dough tools | Dough blade for processor | Dough blade for pitcher | Dough hardware comes with both, used in different large vessels. |
Trade-offs
Change of plan
Go with Nutribullet Triple Prep System. A distinct seven-cup work bowl is included with Triple Prep.
Go with Ninja Foodi Power Blender Ultimate System. Both are included with SS401 in the selected package.
Neither model fits. A dicing grid is not included in either listed bundle.
Decision guide
Nutribullet Triple Prep fits a routine that needs a separate processor bowl and two personal cups. Ninja SS401 fits a routine that wants a dedicated 18-ounce tamper bowl and an extra grating disc. Both slice and shred, with Triple Prep separating processor work from its blending pitcher and SS401 sharing the large pitcher.
When dinner calls for a blended sauce and chopped vegetables, a separate processor bowl spares you from moving the sauce out just to reuse its vessel. Triple Prep gives you that arrangement. Even so, it has one motor base, which means the tasks run in sequence and the extra bowl has to be stored and washed.
Separate drink portions suit Triple Prep's two personal cups. What SS401 offers is one drink cup and a hand-tampered bowl for thicker mixtures. Neither collection is more useful in every case, so line up the supplied containers against the meals you make most often.
Ordinary disc slicing and shredding are covered by both systems. Ninja also lists a grating disc, which may matter for a particular preparation. Since neither listed bundle includes a dicing grid, anyone after repeatable vegetable cubes shouldn’t take a food-processing label as that capability.
