Pro-Release Bakeware Half Sheet Pan vs GreenLife Ceramic Nonstick Cookie Sheet: which is safer?

Where these two actually differ

• We flag PTFE fume risk on thermal decomposition, Coating degradation and particulate shedding and Steel substrate corrosion if coating is breached on the All-Clad and not on the GreenPan.
• We flag Ceramic coating degradation over time, Aluminum leaching from substrate and Coating adhesion and food contamination risk on the GreenPan and not on the All-Clad.
• The All-Clad is PTFE non-stick coating, as disclosed by All-Clad where the GreenPan is ceramic nonstick coating, which is most of the difference in these two grades.
• The gap is 65 points, wide enough that this is not a close call, and the GreenPan is the one to buy.
• We are less certain about the All-Clad grade, at 35% confidence against 78%, because it discloses less.
