"I narrowed my choices to OrientDB and Neo4j. It’s been a couple years since that decision process occurred, but I distinctly remember a few reasons why I ultimately chose OrientDB over Neo4j: Performance benchmarks for OrientDB were very impressive, The OrientDB development team was very active, Cost: OrientDB is free. Neo4j cost more than what I was willing to pay or what I could afford. I forget which it was."
