ProSeries Silicone Baking Mat vs Ama Pear Silicone bowl liner for KitchenAid 5QT mixer single piece baking accessory: which is safer?

Where these two actually differ

• We flag Silicone elastomer degradation under prolonged high heat and Mold or bacterial growth if stored wet on the Fat Daddio's and not on the Kitchenaid.
• We flag Silicone leaching (oligomers), Bacterial or mold growth on degraded surfaces and Thermal degradation and odor release on the Kitchenaid and not on the Fat Daddio's.
• The Fat Daddio's is silicone (elastomer) where the Kitchenaid is Silicone bowl liner, which is most of the difference in these two grades.
• These two are level, close enough that price and fit should decide it rather than our grade.
• We are less certain about the Kitchenaid grade, at 45% confidence against 78%, because it discloses less.
