Better compared to what ? If you try to achieve the same using some scripting of your own or make changes to the source data format and apply a kind of transformation to get that, may be then, performance would be better, because a qv system function is always faster than it's counter part/ equivalent one which is user defined.

Then it should be otherwise, that means loading data as it is should be faster, because that doesn't require any extra operation, while the generic/crosstable load performs some transformations.
