Use measurements if you will, but IME the final arbiter is what your own ears tell you in your own system
With all due respect, this has nothing to do with listening. Or measuring. They measure nothing. They just read about measuring on the internet.
From my experience dealing with these folks, more often than not, these folks don’t even have a stereo system at home (other than an Alexa style speaker, AirPods, or car audio). And often they don’t even like music. They just like to play the audiophile in the audio forums. So you are just wasting your time. Me too, but I kinda of like it, it’s a good exercise is psychology and human behavior
