Neo4j is an excellently supported and mature graph database
What do you like best about the product?
The active development, the large, international community, integrations, available documentation and training, certification programs, online events, friendly UI, easy-to-use query language and APOC.
What do you dislike about the product?
I cannot think of anything serious, but the upgrade process could be more straightforward and not require running multiple upgrades to get to the latest version if you're running a much older one in production.
What problems is the product solving and how is that benefiting you?
As with graph databases, one of the most generous benefits, especially compared to traditional databases, is the relationships between the data that can be easily traversed and help discover hidden connections.
