I'm too lazy to answer everything
Not a rebel at all
But this is my way, you can choose yours.
And even if someone tells me this speaker is perfect technically, and I don't like they way it sounds I won't buy it.
What other factors
Like I said, hearing is also critical, I like brighter sound like Genelec and Sennheiser HD800 others feel they're like nails pushed in their ear drums
I had the KH120, while excellent I did feel it was dark sounding, generally didn't like the sound of that tweeter, on the other hand the first second I hear Genelec I loved the sound (even the tiny 8010)
All the measurements in the world won't make me feel differently.
Also the materiel of the cabinet makes difference to the way it sounds would assume and a billion other factors other than just dry numbers, I like the sound of aluminum cabinets vs wood cabinets for example.
Do they all sound the same just because of the materiel? No, do they have some things in common? Yes.
