yes, for humans names (including prefixes) are usually better.
In a schematron context though there's no standard way of expressing the
required namespace bindings to a following process, so (for machine use)
it's simpler to use the prefix free form which you can just expose as
a string for some later Xpath parser to pick up.
In a system where you have full control of the pipeling mechanisms, the
tradefoffs may well be different...
