4 Piece Cutting Mat Set vs Silicone Grip Mat: which is safer?

Where these two actually differ

• We flag Unspecified surface coating leaching, Rubber degradation and microparticle shedding, Plasticizer or filler migration and Bacterial retention in crevices or seams on the Cuisinart and not on the Silikomart.
• We flag Siloxane leaching (low-molecular-weight oligomers), Microparticle shedding from grip surface and Mold or bacterial growth in surface texture on the Silikomart and not on the Cuisinart.
• The Cuisinart is Rubber or silicone mat with unspecified coating where the Silikomart is silicone rubber grip mat, non-coated, which is most of the difference in these two grades.
• The gap is 65 points, wide enough that this is not a close call, and the Silikomart is the one to buy.
• We are less certain about the Cuisinart grade, at 35% confidence against 82%, because it discloses less.
