I lead our database team for a while, and picked ArangoDB. We started to regret it pretty soon thereafter. While I was there, we found that our cluster would just die. I think they got put fix in for that, though my memory is hazy.
After I left, they came to really regret it. My team was working at scale, and basically found themselves doing QA work, trouble shooting with the Arango team. To their credit, the Arango crew was extremely responsive and helpful. Maybe they've fixed things up since then; it's been a year and a half.
At this point, I would hard pass on any database whose name doesn't start with PostgreSQL. Just got burned too hard.
Graph databases ostensibly let you write queries that would otherwise be unwieldy, but it turns out PostgreSQL's `recursive` keyword lets you achieve roughly the same things, sans having to learn a whole new query language.
