20oz TKWide with Café Cap, Tofu vs 22 oz Vacuum Insulated Stainless Steel Tumbler: which is safer?

Where these two actually differ

• 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 Ozark Trail.
• We flag Lid and gasket degradation and Seal integrity and bacterial growth on the Ozark Trail and not on the Klean Kanteen.
• The Klean Kanteen is Stainless steel bottle, stainless steel cap where the Ozark Trail is Stainless steel interior and exterior, no coating disclosed, which is most of the difference in these two grades.
