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

Where these two actually differ

• We flag Microplastic shedding and Surface degradation and staining 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 Rubber or silicone cutting mats where the Fiskars is Polypropylene or similar plastic; no nonstick or waterproof coating disclosed, which is most of the difference in these two grades.
• We are less certain about the Cuisinart grade, at 35% confidence against 72%, because it discloses less.
