Look at the number of cooking functions, preset programs, and the type of lids each system uses. Instant Pot models focus on 11‑13 functions with a single interchangeable lid, while Nuwave offers up to 540‑in‑1 functions with three removable lids for more specialized modes. Also compare capacity (both 6 qt) and any smart features like Wi‑Fi or app integration that fit your cooking style.

The Instant Pot Duo Crisp and Duo Crisp Ultimate lids hold about 6 quarts, ideal for 4‑6 servings or batch cooking. In contrast, the Emeril Lagasse and COSORI toaster‑oven combos provide 25‑26 qt, allowing you to roast a whole chicken, bake a 12‑inch pizza, or toast multiple slices at once. Choose the larger capacity if you frequently cook for bigger groups or need simultaneous multi‑dish cooking.

EvenCrisp uses precise temperature control and rapid air circulation to achieve a crisp finish with up to 95% less oil, similar to traditional air fryers. The dual‑zone fan in Emeril Lagasse ovens splits the interior into two temperature zones, letting you cook a main dish and a side simultaneously. Both deliver crispy results, but the dual‑zone design offers more flexibility for multi‑component meals.

The Ultimate Lid adds functions like sous vide, yogurt making, and bread proofing, expanding the appliance beyond typical pressure cooking and air frying. If you enjoy experimenting with these specialty techniques, the added versatility can offset the higher cost. For everyday cooks who mainly pressure cook, air fry, and slow cook, a standard Duo Crisp may provide better value.

Nuwave Duet models list up to 300 one‑touch presets plus 240 memory slots, making them the most feature‑rich in terms of saved recipes. Instant Pot’s Duo Crisp Ultimate Lid provides 13 preset functions, while the standard Duo Crisp offers 11, both with fewer custom memory options. If you rely heavily on preset automation, the Nuwave’s extensive library gives you the fastest start‑up.

Wi‑Fi and the Instant Connect app let you follow step‑by‑step recipes, monitor progress, and adjust settings from your phone, which is handy for busy households. Not all models include this feature; only the Instant Pot 6.5 qt Duo Crisp Ultimate Lid lists Wi‑Fi capability. If remote control and recipe integration are priorities, choose a model with built‑in connectivity.

Key safety elements include overheat protection, automatic pressure release, Sure‑Lock lid mechanisms, and clear “OK to Open” alerts on the display. Nuwave highlights 15 safety features such as automatic pressure release and overheat protection, while Instant Pot models emphasize safe steam release and lid lock indicators. Prioritizing devices with multiple redundant safety systems reduces the risk of accidents.

Both brands claim up to 70% faster cooking compared to traditional methods, but Nuwave’s Dynamic Pressure Control technology emphasizes rapid pressure adjustments for quicker results. Instant Pot’s EvenCrisp focuses on efficient air circulation, which can lower energy use during air‑fry cycles. In practice, the differences are modest; choosing based on preferred functions and user interface may be more impactful than minor efficiency gains.
