What we love
- You want maximum cooking versatility -- 13 presets including Sear Crisp, Griddle, and Frozen Pizza modes that no other oven here offers.
- You need 500°F for pizza stone use or high-heat searing and want Dual Heat Technology for faster preheating.
- The Smart Thermometer for internal food temperature monitoring is important to your cooking style.
- You've accepted the unspecified coating and lack of certification as known unknowns.
Worth knowing
- You need to know what coating touches your food -- Ninja won't disclose whether the interior is PTFE or ceramic. At 500°F, this matters more than on any other oven in the comparison.
- You want independently certified electrical safety -- no UL or ETL mark was found for the SP351.
- Safety transparency is a priority -- both the interior coating and safety certification are unresolved. The Instant Omni Plus at $20 less offers a porcelain-enamel interior and UL Listed certification.
