Functional Form Cutting Board Set, 3-Piece vs World Market Joseph Joseph Pop Reversible Chopping Mats: 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 Joseph Joseph.
• We flag Polypropylene degradation or additive leaching and Surface contamination or bacterial trapping on the Joseph Joseph and not on the Fiskars.
• The Fiskars is Polypropylene or similar plastic; no nonstick or waterproof coating disclosed where the Joseph Joseph is Silicone and polypropylene mats, which is most of the difference in these two grades.
• We are less certain about the Joseph Joseph grade, at 35% confidence against 72%, because it discloses less.
