I don't think there is an established best practice related to this 
topic.  Moreover, your choice may depend on your application, use case, 
practical needs, etc. However, as far as I can foresee, using both 
rdfs:Class and owl:Class is perfectly safe wrt to RDF/RDFS tools and 
perfectly safe wrt OWL tools.
