USB-C to USB-C Cable 2-Pack vs Atlas Waterproof Case for iPhone SE / 5s / 5: 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 Incipio.
• We flag Polycarbonate degradation and bisphenol A (BPA) leaching, TPE degradation and oligomer release and Bacterial or fungal growth in trapped moisture on the Incipio and not on the Anker.
• The Anker is PVC outer jacket, copper conductors, standard connectors where the Incipio is Polycarbonate/TPE shell, 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 Incipio grade, at 35% confidence against 78%, because it discloses less.
