Main trade-off
Nutribullet Triple Prep System
A separate work bowl adds another large vessel to store.
Head-to-head
Choose Nutribullet Triple Prep if a separate processor bowl and two personal cups fit your cooking routine. Choose Ninja SS401 for a dedicated 18-ounce tamper bowl and an extra grating disc. Both slice and shred, but Triple Prep keeps processor work separate from its blending pitcher while SS401 shares the large pitcher.
Before you choose
Triple Prep lets a prepared mixture 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 those tasks may require emptying it first.
What this is based on
Triple Prep has one blending pitcher and one separate work bowl. SS401's processing feed-chute lid fits its blending pitcher. Neither base operates two vessels simultaneously.

Triple Prep has one blending pitcher and one separate work bowl. SS401's processing feed-chute lid fits its blending pitcher. Neither base operates two vessels simultaneously.
Triple Prep supplies a 32-ounce cup and a 24-ounce cup, compared with one 24-ounce cup on SS401. A second personal-drink user has an included vessel on Triple Prep, subject to each cup's fill markings.
Two supplied personal cups versus one means one additional personal vessel. The 18-ounce SS401 bowl is a different container with a storage lid.
Triple Prep includes a hand tamper for its pitcher. SS401 supplies an 18-ounce bowl with an integrated tamper. Pick SS401 if the dedicated small thick-blend container is important, without assuming Triple Prep has no tamper at all.

Meaningful differences
| What changes | Nutribullet Triple Prep System | Ninja Foodi Power Blender Ultimate System | Why it matters |
|---|---|---|---|
| Large blending vessel | 64-ounce pitcher | 72-ounce pitcher | These are nominal vessel labels. Each recipe must respect its marked fill limit. |
| Processor arrangement | Separate 7-cup work bowl | Processing lid and discs on the main pitcher | Triple Prep can leave one vessel's contents in place while changing tasks on the base. |
| Personal cups | 32 ounces and 24 ounces | One 24-ounce cup | Triple Prep includes two personal vessels in different sizes. |
| Small tamper bowl | None included | 18-ounce bowl with built-in tamper | SS401 has a dedicated small vessel for thick spoonable blends. |
| Disc tools | Reversible slice/shred disc | Reversible slice/shred disc plus grating disc | Both slice and shred. SS401 adds a separately listed grating tool. |
| Dough tools | Dough blade for processor | Dough blade for pitcher | Both supply dough hardware, used in different large vessels. |
What you give up
Recommendation switch
Choose Nutribullet Triple Prep System. Triple Prep includes a distinct seven-cup work bowl.
Choose Ninja Foodi Power Blender Ultimate System. SS401 includes both in the selected package.
Choose neither. Neither listed bundle includes a dicing grid.
What matters in practice
If dinner needs a blended sauce and chopped vegetables, a separate processor bowl can save transferring the sauce just to reuse its vessel. Triple Prep offers that arrangement. It still has one motor base, so the tasks run sequentially and the extra bowl must be stored and washed.
Triple Prep's two personal cups suit separate drink portions. SS401's combination is one drink cup plus a hand-tampered bowl for thicker mixtures. Neither collection is universally more useful. Compare the supplied containers with the meals you make most often.
Both systems cover ordinary disc slicing and shredding. Ninja also lists a grating disc, which may matter for a particular preparation. Neither listed bundle includes a dicing grid, so shoppers seeking repeatable vegetable cubes should not equate a food-processing label with that capability.
