Master Forge Rectangular Grill Mat vs Tool Mat: which is safer?

Where these two actually differ

• We flag PTFE/fluoropolymer coating degradation and fume release, Silicone or urethane leachate under heat cycling, Fiberglass particle shedding from coating breakdown and Bacterial or mold growth from moisture retention on the GRILL MASTER and not on the Weber.
• We flag Silicone degradation at extreme heat and Off-gassing of volatile organic compounds (VOCs) on the Weber and not on the GRILL MASTER.
• The GRILL MASTER is fiberglass mesh or silicone-coated fabric (unspecified) where the Weber is Silicone mat or rubber composite, 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 Weber is the one to buy.
• We are less certain about the GRILL MASTER grade, at 35% confidence against 72%, because it discloses less.
