20oz TKWide with Café Cap, Tofu vs Classic Tumbler with Straw & Flip Lid: 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 Simple Modern.
• We flag Plastic degradation and microplastics when heated and Lid/straw material composition uncertainty on the Simple Modern and not on the Klean Kanteen.
• The Klean Kanteen is Stainless steel bottle, stainless steel cap where the Simple Modern is Stainless steel tumbler, plastic lid/straw, 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.
