Port 30oz Tumbler with Carry Loop & Integrated Handle vs 20oz TKWide with Café Cap, Tofu: which is safer?

Where these two actually differ

• We flag Plastic/elastomer lid and gasket composition, Gasket and seal degradation over time and Carry loop and attachment durability on the Ello 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 Ello.
• The Ello is Stainless steel tumbler with plastic/elastomer lid and carry loop where the Klean Kanteen is Stainless steel bottle, stainless steel cap, 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.
