CPC-900 6 Quart High Pressure Multicooker vs Mini Chef Series 4QT Multi-Cooker: which is safer?

Where these two actually differ

• We flag Silicone gasket degradation and odor retention and Plastic off-gassing (base housing) on the Cuisinart and not on the Instant Pot.
• We flag Sealing ring degradation and odor absorption, Stainless steel surface pitting and corrosion and Thermal injury from steam or pressure release on the Instant Pot and not on the Cuisinart.
• Both carry a flag for Pressure release valve clogging, so neither choice avoids it.
• The Cuisinart is Stainless steel inner pot, electric heating base where the Instant Pot is Stainless steel pot/bowl, no nonstick coating disclosed, 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.
