CPC-900 6-Quart High Pressure Multicooker - 15psi Electric Pressure Cooker vs Nationalpresto Presto Pressure Cooker and Canner 01755: which is safer?

Where these two actually differ

• We flag Seal and gasket degradation, Aluminum outer housing corrosion or leaching and Pressure relief valve blockage on the Cuisinart and not on the Presto.
• 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 Cuisinart.
• The Cuisinart is Stainless steel inner pot, aluminum outer housing where the Presto is stainless steel body; no nonstick coating, 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.
