CPC-600 6 Qt Electric Pressure Cooker vs Mini Chef Series 4QT Multi-Cooker: which is safer?

Where these two actually differ

• We flag Silicone sealing ring degradation, Stainless steel corrosion or pitting, Thermal shock or pressure seal failure from improper use and Mineral or food residue buildup on heating element on the Cuisinart and not on the Instant Pot.
• We flag Sealing ring degradation and odor absorption, Stainless steel surface pitting and corrosion, Pressure release valve clogging and Thermal injury from steam or pressure release on the Instant Pot and not on the Cuisinart.
• The Cuisinart is Stainless steel cooking vessel; sealed electric heating element 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.
