I said poor not unfair. They might happen to end up with equal price per flash chip, but either could end up being more expensive it’s just not a good yardstick IMO.

Anyway, what you might consider insignificant differences are things companies do consider these worth paying for. You not caring isn’t the same thing as nobody caring.

> significantly affected by the choice of controller

Aka it is more complicated than just slapping different controller on the same chips and calling it a day.
