36-in Silicone-Coated Mat vs Functional Form Cutting Board Set, 3-Piece: which is safer?

Where these two actually differ

• We flag Silicone coating degradation and leaching, Base layer composition and leaching and Off-gassing or odor during first use on the Cuisinart and not on the Fiskars.
• We flag Microplastic shedding from cutting action, Bacterial biofilm accumulation in deep cuts, Staining and odor retention and Heat-induced warping or leaching on the Fiskars and not on the Cuisinart.
• The Cuisinart is silicone-coated (unspecified base and coating details) where the Fiskars is Polypropylene or similar plastic; no nonstick or waterproof coating disclosed, 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 Fiskars is the one to buy.
• We are less certain about the Cuisinart grade, at 35% confidence against 72%, because it discloses less.
