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

Where these two actually differ

• 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 Presto.
• We flag Nonstick coating degradation and inhalation (PTFE fume risk), Aluminum leaching from pot or seals, Coating durability and unknown composition and Pressure seal and gasket leachables on the Presto and not on the Instant Pot.
• The Instant Pot is Stainless steel pot/bowl, no nonstick coating disclosed where the Presto is Stainless steel body; inner pot/lid coating unspecified, which is most of the difference in these two grades.
• The gap is 60 points, wide enough that this is not a close call, and the Instant Pot is the one to buy.
• We are less certain about the Presto grade, at 45% confidence against 78%, because it discloses less.
