/// I buy the strings that I know suit my ear, and I care not a jot whether they suit anyone else.////

Nobody else will care. The only time the strings matter is when they're wearing out and sounding clunky. As long as they have life in them, they sound the same as any other strings with life in them.

They're strings. A string is a string. You pluck it and it vibrates. As long as it is not brittle from from wear and can vibrate reasonably well, it sounds like every other string in that same condition.

I think what it is with many people is that there is an undeniable difference in the way a newly-installed string sounds as opposed to one that's broken in. I've even read about guitarists who change their strings every few days because they have to have that very bright, crisp sound of a new string. But that quality is very fleeting, it's not the normal sound of the string. It's like popping a new piece of chewing gun in your mouth every five minutes because the flavor fades away. Waste of gum but the gum manufacturer thanks you. If anything, they'll make the flavor even more intense and more fleeting to keep you using up more gum faster and therefore buying more gum faster and increasing their profit margins.

But brand new strings after a week of stready playing sound the same no matter what brand they are. It's silly to argue it. It's like someone saying, "My gum still has more flavor in it after an hour of chewing than the other brands." No, it doesn't.
