Either way, I do recall that the price difference was reflected between the two.
e.g.,
E90 water pumps are more expensive because they are "digital"
E46 and prior water pumps were "mechanical" and are cheaper because of that.
Someone please correct me if I am wrong...

The water pump is driven by an electric motor using DC electrical power. A "digital" water pump makes no sense. And they are actually a lot easier to replace.
