How We Choose the Products We Recommend
We don’t have a warehouse full of gear to physically put through its paces — what we do instead is disciplined research. For every guide, we start with the manufacturer’s published specifications and compare them directly against competing models in the same price range. We track real, current pricing across retailers, not list prices that never actually apply, so the numbers in our comparisons reflect what you’d actually pay today. And we read, in bulk, through verified customer reviews and independent expert coverage for each product, looking for recurring complaints, common praise, and the patterns a single glossy product page won’t tell you.
Where we’ve personally bought and used a product ourselves — currently true for many of the kitchen items we cover — we say so directly in the review, and that firsthand experience shapes what we highlight. For everything else, our pros-and-cons calls come from that cross-referenced research process, not a single source or a rewritten spec sheet. We revisit guides periodically as prices shift and new models launch, and we link to multiple retailers where possible so you’re not stuck with just one option.

Ninja and Cosori dominate the countertop air fryer market for good reason: both brands deliver crispy, evenly cooked food without the guesswork of older models. But they take different approaches — Ninja leans into dual-zone baskets and rugged build quality, while Cosori focuses on touchscreens, app connectivity, and slightly gentler prices. We compared two current models from each brand, matched roughly by size and price tier, to see which one actually earns a spot on your counter. Here’s how the Ninja AF101, the Foodi 2-Basket, the Cosori Pro II, and the DualBlaze stack up on capacity, price, and everyday cooking performance.

1. Ninja Air Fryer (AF101) — Best Ninja Value
The AF101 is the air fryer that kicked off Ninja’s dominance in this category, and it still holds up years later if you just want one basket done well. The 4-quart ceramic-coated basket preheats fast, and crisping results hold up well against newer, pricier Ninja models for fries, wings, and reheated leftovers. Compared to Cosori’s equivalent single-basket models, the AF101’s dial-and-button interface is less flashy, no app, no touchscreen, but it’s close to foolproof with fewer things to break. The 4-quart capacity is the real limiting factor: it’s tight for family-size batches, and there’s no dual-zone option like Ninja’s own Foodi line or Cosori’s DualBlaze. As a compact, no-fuss fryer for smaller households, it’s one of the best value picks in either brand’s lineup.
Pros: Reliable crisping at a low price, Simple dial controls, nothing to malfunction, Compact footprint for small kitchens, Easy-to-clean ceramic-coated basket.
Cons: Only 4-quart capacity, tight for families, No app or dual-zone cooking.
2. Ninja Foodi 6-in-1 2-Basket Air Fryer (DZ201) — Best Ninja Overall
This is the Ninja model most worth comparing directly against Cosori’s best, because DualZone cooking is genuinely useful in a way marketing gimmicks often aren’t. Two independent 4-quart baskets let you cook fries and chicken at different times and temps and have them finish together via Match Cook, something Cosori’s single-basket Pro II simply can’t replicate, only Cosori’s own DualBlaze competes here. Six functions (air fry, roast, bake, broil, reheat, dehydrate) cover real weeknight cooking, and build quality feels noticeably sturdier than Cosori’s plastic-forward housings. It’s bulkier on the counter than either Cosori option, and cleaning two baskets takes longer than one. But for a family that actually cooks multiple components per meal, the DZ201 is the single most versatile air fryer either brand sells at this price.
Pros: Two independent zones cook different foods at once, Match Cook syncs finish times, 6 cooking functions in one unit, Sturdy build quality.
Cons: Large counter footprint, Two baskets mean more cleanup.
3. Cosori Pro II 5.8-Qt Smart Air Fryer — Best Cosori Overall
Cosori’s Pro II is the company’s answer to Ninja’s single-basket dominance, and in day-to-day cooking it holds its own. The 5.8-quart square basket actually fits more food than Ninja’s 4-quart AF101 at similar pricing, and the touchscreen with app connectivity (13 presets, shake reminders, Alexa/Google voice control) feels more modern than Ninja’s dial interface. Cosori’s basket coating has historically felt a notch below Ninja’s in long-term durability, and the plastic housing runs a bit warmer to the touch during long cooks. There’s also no dual-zone cooking here, so if independent-temperature multitasking matters, the Foodi DZ201 or Cosori’s own DualBlaze both beat it. For solo cooks and couples who want a bigger single basket with smarter controls than Ninja’s base model, though, the Pro II is the better buy of the two brands’ entry points.
Pros: Larger 5.8-qt basket than Ninja’s base model, App and voice control support, Touchscreen with 13 cooking presets, Competitive pricing vs. Ninja.
Cons: No dual-zone cooking option, Basket coating wears faster than Ninja’s over time.
4. Cosori DualBlaze 6.8-Qt Smart Air Fryer — Best Cosori Value
DualBlaze is Cosori’s direct shot at Ninja’s Foodi 2-Basket, and remarkably it often sells for the same price as Cosori’s own single-basket Pro II while adding a second independently controlled zone. Sync Cook and Sync Finish mirror Ninja’s Match Cook feature almost exactly, and the touchscreen interface is easier to navigate one-handed than Ninja’s button layout. Where it falls short of the DZ201 is raw heating power and long-term basket coating durability, Ninja’s baskets have historically held up better after heavy use. Still, at $129.99, getting two independently controlled zones makes DualBlaze the sharper value in Cosori’s own lineup, and arguably the best dollar-for-dollar dual-zone fryer on this list overall.
Pros: Dual-zone cooking at single-basket pricing, Sync Cook/Sync Finish rival Ninja’s Match Cook, Easy-to-use touchscreen, Ceramic-coated baskets.
Cons: Basket coating durability trails Ninja long-term, Slightly less powerful heating than Ninja Foodi.
