Why choose it: A two-cup processor covers small chopping and slicing jobs.

What matters when choosing
Tiny Prep Bowl or Complete Kitchen System?
Both machines use one motor base for drinks and some food prep, but they suit very different kitchens. nutribullet Ultra Plus 2-in-1 is centered on personal smoothies and a tiny two-cup processor. Triple Prep adds a family-size pitcher, two personal cups and a seven-cup processor. The deciding question is not which has the grander name; it's whether you cook for one or regularly prepare dinner for several.
What you'll actually notice
The US Ultra Plus NB20550ID includes a 32-ounce cup, a double-walled 24-ounce cup, and a two-cup processing bowl with chopping and reversible slice/shred accessories. The Triple Prep NBKS50100 includes a 64-ounce pitcher, 32- and 24-ounce cups, seven-cup processor, plus slicing/shredding and dough tools.
One system is compact personal blending with the occasional small vegetable job. The other is a larger family setup with more specialized vessels. Both can create clutter if you rarely use their attachments.
What changes the choice
Two cups of food prep is genuinely small
Ultra Plus's processor is suitable for modest chopping or slicing jobs: a few herbs, one onion or a little shredded cheese. You don't have to wash a large processor just to prepare a garnish. The reversible disc is real processing hardware, not a blade in a smoothie cup.
Two cups will quickly become frustrating if you're shredding cabbage for four or preparing a substantial soup base. Triple Prep's seven-cup bowl can reduce repeated batches and adds a dough blade for the appropriate recipes. Follow each model's working limits rather than filling any bowl to its nominal capacity.
What you blend each day
Ultra Plus is fundamentally a personal-cup machine. Its two cups suit smaller and larger single servings, but there is no big pitcher for several drinks in one batch. If a couple both make separate smoothies, the personal format may be enough.
Triple Prep adds the 64-ounce pitcher, so it can handle shared smoothies or frozen drinks without repeated small-cup cycles. That benefit is real only when several servings are part of your routine. If the pitcher lives unused in a cabinet, you've bought extra glassware without a benefit.
Don't confuse two-in-one with three-in-one
The NB20550ID standard two-in-one box does not include the coffee-and-spice grinder marketed with the separate three-in-one Ultra Plus NB50550AKID configuration. That matters if grinding coffee is part of your breakfast plan; the model suffix changes the equipment.
Triple Prep doesn't become a coffee grinder merely because it has a food processor bowl. Check exact manufacturer-approved attachments and use only the accessories matched to the base. Don't improvise by fitting a blade from another nutribullet family.
Power is not a chopping comparison
Ultra Plus advertises 1,200 watts and Triple Prep advertises 1,500. Those are manufacturer electrical figures, not measured differences in smoothie texture, blade longevity or carrot-shredding accuracy. The larger machine's capacity and tool set are the meaningful, verified upgrades.
If you care most about smooth kale drinks or fine ice, look for independent tests of each exact US configuration. Neither should receive an invented head-to-head score from another nutribullet model or a retailer's aggregate stars.
Storage and the daily sink
Ultra Plus has more pieces than an ordinary smoothie maker, but its two-cup processing bowl is small. Triple Prep requires storage for a big pitcher and seven-cup processor, in addition to personal cups and multiple blades. Consider where everything will dry.
Use the manufacturer-specific dishwasher, blade and lid instructions. Neither sealed personal cup should be assumed safe for steaming soup. Those are safety requirements, not optional preferences.
Purchase conditions are a real consideration
The Ultra Plus two-in-one manufacturer listing has shown an out-of-stock indication; that doesn't prove every US seller is out, but it does mean availability needs a current check. Triple Prep also requires confirmation of the exact NBKS50100 package rather than a differently configured nutribullet bundle.
No live USD offer is certified here. Decide whether you'd use a full pitcher and large processor every week, then compare dated seller prices and included components.
The practical choice
Ultra Plus suits personal drinks plus tiny occasional prep. Triple Prep is for households that genuinely alternate among family smoothies, individual drinks, and full-size vegetable preparation. Bigger is only better when you need the volume.
When to choose Ultra Plus 2-in-1
Choose it for one-person smoothies and small chopping or slicing jobs. The two-cup processor is its defining compromise and keeps the machine's role appropriately modest.
When to choose Triple Prep
Choose it when a seven-cup processor and family pitcher would replace appliances you already use. The extra dishes and storage make sense only when those jobs occur regularly.
Choose neither when
A single-purpose blender may be easier if you never prepare vegetables. A full dedicated processor may be better if slicing and dough dominate but blended drinks are rare. For precision dicing, choose an included dicing grid instead.
PIQSY conclusion
Ultra Plus is the small-kitchen option; Triple Prep is the multi-job family system. Their processor bowls are dramatically different sizes. Start with how many meals and smoothies you prepare, then verify the exact US box and current offer.
