In my opinion all that matters is you pick a system that suits you to gauge relative quality. I like my SQM and use it at every dark site I go to and the backyard and in terms of realative darkness it is a good measure but it cannot measure 'seeing'- that is still subjective for most peope as eye sight, age, etc affect it as well as atmo, heat, angle of view through the atmo, etc.
