One other thing I haven't seen anyone tackle is to evaluate 'best' durable via first principles equations and engineering.
Ex of a fridge:
* Define the physics of how the product performs over its life: physics of door opening and effort to lift the door, compressor energy to turn on, vibration life cycles and wear, power converter wear, etc.
* Define theoretical best performance for the product for each use case in fundamental physics.
* Get performance data for real test units.
* OR if testing real units is too expensive and time consuming. Put modeled fake units in a physics simulation engine (like https://docs.unity3d.com/Manual/PhysicsSection.html) and stochastically seed millions of virtual units with minor differences and virtually test to failure.
This would result in a much stronger measure of 'best' durable, that then, the crowd-sourced reviews would, hopefully, reiterate.
