27oz Wide Water Bottle with Loop Cap vs 18 oz Water Bottle with Straw Cap in Royal Blue: 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 YETI Rambler.
• We flag Plastic cap degradation and leaching and Bacterial growth in straw assembly on the YETI Rambler and not on the Klean Kanteen.
• The Klean Kanteen is 18/8 stainless steel, no interior coating where the YETI Rambler is Stainless steel interior, plastic lid/cap, 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.
