The subtle difference on where these two can be used may become a frequent source of error I am afraid... My preference would be to pick one of the two and use it everywhere. As an aside... I wonder whether JSON-LD should not adopt, as an advanced and optional feature, the additional vocabulary expansion approach that RDFa1.1 does on @vocab/@base. At least for RDF usage it might be extremely useful...
