one more thing to consider... while it probably won't have that much of an impact with Jackrabbit 2.x the situation is different with Jackrabbit Oak. Oak currently comes with default indexes for jcr:primaryType and jcr:mixinTypes. If you now turn your query into 'FROM nt:base' Oak won't be able to leverage those indexes and the query will be terribly inefficient. You will have to add an index on sling:vanityPath to make if efficient again.
