USB-C to USB-C Cable 2-Pack vs Nest Cam Charging Cable 2 Pack: 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 Google.
• We flag Polymer jacketing degradation and off-gassing and Connector corrosion or material leaching into devices on the Google and not on the Anker.
• The Anker is PVC outer jacket, copper conductors, standard connectors where the Google is USB cable with standard polymer jacketing, 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.
