We all know that brand 'x' is 'the best' possible tool available.
So why doesn't everybody use brand 'x' ?
Well, because some people have gotten used to brand 'y' and it is good enough for them.
What's better doesn't enter in to it. There is a minimum level of performance required for the job and both tools meet those requirements, so both are valid tools to solve the problem with.
Which one is the 'better' one is a matter of perspective, and in that sense there are as many truths as there are observers.
That's not what I wrote. It's simply good enough.
