NS Pro Nonstick Double Burner Griddle vs Rio Advanced Ceramic Nonstick Griddle: which is safer?

Where these two actually differ

• We flag PTFE thermal degradation and fume release, Coating degradation and microflaking, Aluminum leaching from base or exposed substrate and PTFE manufacturing residue (PFOA/PFBS) on the All-Clad and not on the GreenPan.
• We flag Coating degradation and substrate exposure, Aluminum leaching and Manufacturing consistency and third-party verification 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-based 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 72%, because it discloses less.
