20oz TKWide with Café Cap, Tofu vs Insulated Wall Vacuum Stainless Steel Water Bottle Tumbler 17oz: 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 Mira.
• We flag Lid/gasket material degradation or off-gassing and Bacterial or mold growth in seams on the Mira and not on the Klean Kanteen.
• The Klean Kanteen is Stainless steel bottle, stainless steel cap where the Mira is Stainless steel interior, vacuum-insulated double-wall construction, which is most of the difference in these two grades.
• The gap is 25 points, wide enough that this is not a close call, and the Klean Kanteen is the one to buy.
