I respectfully disagree with you, my young friend, as to it not mattering. It does to me.

I'm have a pretty good idea as to what HCH9 chips can do at various voltages. The experience with HCK0 is pretty restricted, mostly to Samsung generic, so we don't really know whether they have been limited by such things as the layout of the PCB used by Samsung on the LV / LP modules, or whether they don't clock as high, but if you sample results from known HCH9 based stuff, compared to known HCK0 the odds are that the former will best the latter. For the same dollars I'd rather get HCH9 in my modules.
