Where these two actually differ
- We flag Nonstick coating thermal degradation and fume risk, Coating particle ingestion if basket degrades and Off-gassing from interior surfaces during first use on the Breville and not on the Ninja.
- We flag Thermal fracture or stress in glass cooking vessel, Plastic housing off-gassing (VOCs and formaldehyde) and Electrical hazard or heating element degradation on the Ninja and not on the Breville.
- The Breville is Stainless steel body; nonstick basket/tray coating unspecified where the Ninja is Glass cooking vessel with stainless steel and plastic components, which is most of the difference in these two grades.
- The gap is 60 points, wide enough that this is not a close call, and the Ninja is the one to buy.
- We are less certain about the Breville grade, at 35% confidence against 75%, because it discloses less.
