The -delete action corresponds to a direct call to unlink.  Therefore
it is faster than the "-print0 | xargs" method.  In theory on some
systems xargs -P could be faster (i.e. ones with many CPUs and many
spindles) but it's rather unlikely.

I'd expect the difference to be measurable for deep directory
hierarchies, but have not measured it myself.

I agree.  The conceptual cost of the additional complexity outweighs
the benefit.
