27oz Wide Water Bottle with Loop Cap vs 30oz Mesa Loop Water Bottle with Covered Spout: which is safer?

Where these two actually differ

• We flag Cap or closure contamination and Bacterial or mold growth from moisture retention on the Klean Kanteen and not on the Simple Modern.
• We flag Plasticizer leaching under heat stress, Microplastics from surface degradation and Bacterial growth in covered spout mechanism on the Simple Modern and not on the Klean Kanteen.
• The Klean Kanteen is 18/8 stainless steel, no interior coating where the Simple Modern is BPA-free plastic (Tritan or similar copolyester), which is most of the difference in these two grades.
• The gap is 30 points, wide enough that this is not a close call, and the Klean Kanteen is the one to buy.
