Cypher is a graph query language for Neo4j and AgensGraph
Gremlin is the graph traversal language and virtual machine of Apache TinkerPop™
"Recently we noticed that cypher queries run faster than gremlin so we decided to convert our queries"
from question "Neo4j - Issue converting gremlin query to cypher"
"In this case a traversal-oriented approach is best maybe gremlin is better since cypher doesn t allow you to specify traversal order"
from question "Cypher's and Gremlin's Grammar and Semantics"
"But i read in this post that group by on union are not possible yet it mean that cypher is less powerful than gremlin"
from question "Cypher union group by sum"
"Neo4j and cypher is still faster and obviously this has no effect on the gremlin queries on neo4j but that might be just a issue with the gremlin implementation for neo4j"
from question "Are Blueprints/Gremlin graph DB queries inherently slow?"
|Much more clear||
"Cypher seems much more clear to me than gremlin and in general it seems that the guys in neo4j are going with cypher"
