Nationalpresto Presto Pressure Cooker and Canner 01755 vs Electric Pressure Cooker 6Qt: which is safer?

Where these two actually differ

• We flag Gasket and sealing material degradation and Stainless steel corrosion and leaching under acidic or salt conditions on the Presto 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 Presto.
• The Presto is stainless steel body; no nonstick coating 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 Presto is the one to buy.
• We are less certain about the Presto grade, at 45% confidence against 85%, because it discloses less.
