Rambler 24 oz Mug with Ceramic Lining vs Rambler 18 oz Water Bottle with Straw Cap in Cape Taupe: which is safer?

Where these two actually differ

• We flag Ceramic coating degradation over time, Bacterial growth in crevices or damaged coating and Thermal shock or fracture on the Yeti and not on the Yeti.
• We flag Plastic cap material identity and leaching, Bacterial and mold growth in cap and straw and Cap degradation and microplastic shedding on the Yeti and not on the Yeti.
• The Yeti is stainless steel exterior, ceramic lining interior where the Yeti is 18/8 stainless steel interior and exterior with plastic straw cap, which is most of the difference in these two grades.
