Simply Calphalon Nonstick Bakeware 9-Inch Round Cake Pan vs Original Bundt Pan 12 Cup: which is safer?

Where these two actually differ

• We flag Nonstick coating thermal stability (unspecified chemistry), Coating degradation and flaking, Substrate leaching (aluminum if used) and Uneven heat distribution and hotspots on the Calphalon and not on the Nordic Ware.
• We flag Coating degradation over time and Rust or iron oxidation from improper storage on the Nordic Ware and not on the Calphalon.
• The Calphalon is Nonstick coating (type unspecified, proprietary) where the Nordic Ware is Cast iron with natural seasoning, which is most of the difference in these two grades.
• The gap is 80 points, wide enough that this is not a close call, and the Nordic Ware is the one to buy.
• We are less certain about the Calphalon grade, at 35% confidence against 88%, because it discloses less.
