I have read the article. Somewhere in the essay it says:
"(keep in mind that Spinorama measurements are done in an anechoic chamber)"
Controlled environment!! My room is not an anechoic chamber.
Spinorama or even simple frequency response or on-axis/off-axis graphs are not useless. They have their use.
Though it is daunting for a non-technical person to interpret what it means for in-room performance with a human involved.

Spinorama also measures how the room reflections will effect it's performance.

In the above sentence, change "will" to "may" and it makes more sense
That's why I listed out my "order of specs/factors" that I would consider, followed by "user subjective opinions".
Both of the above given appropriate weight. The youtube guy also says this, at least that's why I gleaned out of it.
Measurements form the base, after which "user subjective opinions" should be sought or read up to complete the story.
