New Neo4J marketing campaign

This morning I've read a tweet by Emil Eifrem, CEO of Neo Technology (the company behind Neo4J product).

Do they really had to spend the $ 10.6 Million of dollars received in funding in this marketing operation?

If Open Source OrientDB wasn't SUPERIOR (faster, smarter and more complete) to the OVERPRICED Neo4j, Neo4j wouldn't be so obsessed with campaigning against it.

To remain in the telco field #Neo4J is like #Nokia: leader for a while but didn't innovate. And then came #OrientDB...

The popularity of OrientDB grows up so fast!

Sometimes I check the site DB-Engines.com with the ranking of DBMS products in popularity (this is the method they use). I'm not surprised to see OrientDB at the second position in Graph Database market right after Neo4J. Neo4J has a score of 9.73 against OrientDB with "only" 0.92.

But the most interesting thing is the grow up factor: OrientDB is at +22,8% while Neo4J is at "only" +8,3. So can OrientDB surpass Neo4J in terms of popularity? What are the pros and cons of OrientDB against Neo4J? Any comments is welcome, also in private.
