The following document was prepared by Stefan Plantikow (Neo4j Cypher language designer).
It compares the three closely-related languages, PGQL, Cypher and G-CORE, which The GQL Manifesto proposes to be fused into a new standard GQL language, exploiting the very heavy overlap of their current and intended functionality.
There are clickable links to the specs/papers that describe the three languages within this document.
