I used the same technologies, but neo4jrb did have a few rough spots. The change from v7 to v8 was a large, breaking change, and I ran into a number of (minor) compatibility issues with other libraries.

As you say, the appropriate use of a graph database is highly situational. I certainly would not advise doing so without a great deal of careful consideration. However, I tend to doubt whether any amount of consideration would be sufficient; it may be that the most reliable way to determine whether a graph database is the best solution is to try it and see. At least, I was never really able to stop wondering whether I might be able to do things just as easily using Postgres; I would defer to those with more experience, however.
