Legacy 18 x 13 Inch PFA Free Nonstick Cookie vs Amazon.com: WMKGG 9x11 Inches Parchment Paper Sheets,170 PCS Non-Stick Precut Baking Parchment, for Cuisinart Air Fryer: which is safer?

Where these two actually differ

• We flag Nonstick coating degradation over time, Coating fume release at high temperature and Microplastics from coating shedding on the Calphalon and not on the Cuisinart.
• We flag Non-stick coating composition (unspecified), Coating degradation and particulate release and Thermal stability of unidentified coating on the Cuisinart and not on the Calphalon.
• The Calphalon is Steel with PFA-free nonstick coating where the Cuisinart is Parchment paper with non-stick coating, composition unspecified, which is most of the difference in these two grades.
• The gap is 70 points, wide enough that this is not a close call, and the Calphalon is the one to buy.
• We are less certain about the Cuisinart grade, at 35% confidence against 72%, because it discloses less.
