USB-C to USB-C Cable 2-Pack vs Waterproof Pouch: which is safer?

Where these two actually differ

• We flag Copper conductor corrosion and oxidation, Thermal degradation of PVC jacket and Microplastic shedding from jacket wear on the Anker and not on the Case-Mate.
• We flag Phthalates (if PVC-based), Polymer off-gassing (volatile organic compounds), Microplastic fragmentation from wear and Bacterial growth in poorly maintained seals on the Case-Mate and not on the Anker.
• The Anker is PVC outer jacket, copper conductors, standard connectors where the Case-Mate is Synthetic polymer pouch, material not fully described, 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.
• We are less certain about the Case-Mate grade, at 35% confidence against 78%, because it discloses less.
