Rice Cooker with Outer Steam Tray vs Neuro Fuzzy Rice Cooker & Warmer: which is safer?

Where these two actually differ

• We flag Nonstick coating degradation (if PTFE-based), Aluminum leaching (if bare aluminum inner bowl) and Bacterial or mold growth in steam tray on the Aroma and not on the Zojirushi.
• We flag Stainless steel nickel content and Rubber gasket off-gassing or degradation on the Zojirushi and not on the Aroma.
• The Aroma is Stainless steel body; inner cooking bowl coating unspecified where the Zojirushi is Stainless steel inner pot, aluminum outer housing, 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 Zojirushi is the one to buy.
• We are less certain about the Aroma grade, at 45% confidence against 72%, because it discloses less.
