Water Storage Treatment 2 oz Glass Bottles 60 gallons Purification vs Water Bottle: 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 Silicone/plastic gasket 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 Double-wall stainless steel (primary container material), which is most of the difference in these two grades.
• These two are 5 points apart, close enough that price and fit should decide it rather than our grade.
