The measurements don’t lie, but the two charts that people use to evaluate loudspeakers here do not give the full picture.
I know, it would’ve been lovely to measure directivity and frequency response, and rank products accordingly—which is done here quite often and erroneously. Speakers have a sound signature that isn’t remotely captured by those 2 measures; and often that signature is more important to audiophiles than vertical sound dispersion—for example. (After all, they aren’t in a studio environment, moving about, rather in a fixed position throughout the listening session).
It's not a matter of people “getting it wrong”, as you frame it. You and others are entitled to consider the “One” the bee’s knees, as much as I and others find its sound to be lacking. Here we just have to agree to disagree; a matter of taste.
However, to claim that the “Ones” are superior to the mains can’t be done in good faith without auditioning them all in the same room. I actually own both, so I can report that the mains are hands-down more euphonic. Incidentally, I’m no alone: that observation is voiced by many others who are familiar with the mains: from GearSpace professionals to Genelec user forum’s participants.
But hey, test for yourself. If you reach the same conclusion, perhaps you can be the bright brain to discover the missing sound signature measure that will finally solve that puzzle.
