Water Storage Treatment 2 oz Glass Bottles 60 gallons Purification vs Explorer with Flip Straw Lid: which is safer?

Where these two actually differ

• We flag Chemical overdose or misuse, Degradation and loss of efficacy over time, Glass bottle breakage and spillage and Chlorine residue and taste/odor on the Aquamira and not on the S'well.
• We flag Polypropylene lid degradation and Bacterial growth in lid mechanism on the S'well and not on the Aquamira.
• The Aquamira is glass bottles, sodium dichloroisocyanurate treatment chemical where the S'well is Stainless steel bottle with polypropylene lid and flip straw, which is most of the difference in these two grades.
• These two are level, close enough that price and fit should decide it rather than our grade.
