Autoseal FreeFlow Stainless Steel Insulated Water Bottle vs 20oz TKWide with Café Cap, Tofu: which is safer?

Where these two actually differ

• We flag Elastomer gasket and closure degradation, Volatile organic compound (VOC) off-gassing from cap or interior and Bacterial biofilm growth in seal crevices on the Coleman and not on the Klean Kanteen.
• We flag Powder-coat cap degradation over time, Bacterial biofilm in cap threads and seals and Thermal stress on seals at extreme temperatures on the Klean Kanteen and not on the Coleman.
• The Coleman is Stainless steel interior and exterior, no coating disclosed where the Klean Kanteen is Stainless steel bottle, stainless steel cap, which is most of the difference in these two grades.
