Where these two actually differ

• We flag PTFE thermal decomposition and fume risk, Coating degradation and microparticle shedding, Fiberglass substrate exposure and Leaching of coating binders or additives into food on the and not on the Weber.
• We flag Silicone additive/filler contamination (unspecified), Thermal degradation at extreme temperatures, Microplastic shedding if mat degrades and Coating degradation or peeling on the Weber and not on the .
• The is Unknown non-stick coating; fiberglass or silicone substrate presumed where the Weber is silicone (no nonstick fluoropolymer coating disclosed), which is most of the difference in these two grades.
• The gap is 50 points, wide enough that this is not a close call, and the Weber is the one to buy.
• We are less certain about the grade, at 35% confidence against 78%, because it discloses less.
