Nationalpresto Presto Pressure Cooker and Canner 01755 vs 6qt Stainless Steel Pressure Cooker with Straining Basket: 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 T-fal.
• We flag Gasket and sealing ring degradation, Stainless steel minor pitting and corrosion and Pressure release valve blockage or malfunction on the T-fal and not on the Presto.
• The Presto is stainless steel body; no nonstick coating where the T-fal is Stainless steel body and lid, 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.
