Functional Form Cutting Board Set, 3-Piece vs Wonder Mat: which is safer?

Where these two actually differ

• 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 Tupperware.
• We flag Silicone oligomer leaching, Thermal degradation and breakdown, Microparticle shedding from wear and Bacterial biofilm if not dried thoroughly on the Tupperware and not on the Fiskars.
• The Fiskars is Polypropylene or similar plastic; no nonstick or waterproof coating disclosed where the Tupperware is Silicone baking mat, which is most of the difference in these two grades.
• We are less certain about the Tupperware grade, at 42% confidence against 72%, because it discloses less.
