Smart Oven Pro Convection Toaster vs Oil Less Fryer Air Fryer 16 Quart Replacement Clear Glass: which is safer?

Where these two actually differ

• We flag Heating element degradation / oxidation under repeated high heat, Crumb tray and interior dust accumulation and Stainless steel corrosion / leaching under acidic food contact on the Breville and not on the Big Boss.
• We flag Thermal shock and fracture and Edge chipping and glass fragments on the Big Boss and not on the Breville.
• The Breville is stainless steel exterior; interior crumb tray and heating elements (typical toaster oven construction) where the Big Boss is borosilicate glass, bare uncoated, which is most of the difference in these two grades.
• These two are level, close enough that price and fit should decide it rather than our grade.
