USB-C to USB-C Cable 2-Pack vs A601 Universal Waterproof Case: 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 Spigen.
• We flag TPU material degradation and leaching and Seal integrity and microorganism growth on the Spigen and not on the Anker.
• The Anker is PVC outer jacket, copper conductors, standard connectors where the Spigen is TPU/silicone waterproof case, 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 Spigen grade, at 35% confidence against 78%, because it discloses less.
