I personally really like RDF graph databases, because while they look like graph databases such Neo4J they might be implemented completely different. For example Virtuoso is one that is fast for some query types and underneath it is a columnar relational database. GraphDB by ontotext is a custom only SPARQL implementation. Queries that work in one will work in the other (bugs excepted :( ) the only thing that changes is what are they fast at :). Side benefits is that you get a decent JSON api for free with JSON-LD and JSON-SPARQL.

When ever I try Neo4J and Cypher it just feels slow and limited in comparison to the semweb competition.
