The most recent graph DB I've used was Dgraph, I've found the interface to be good to work with and it does scale well performance wise. Memory consumption was still too high for my tastes and if you need to build common algos on top like PageRank, again for example, they don't support that out of the box. If you read through their forum you'll see they may never choose to support things like that natively so you have to do things like I did which was export the data out. This was maybe 7 months ago now.

I'll also say that working on the entire graph if you need to is difficult, they're not oriented around working on the whole more like fragments that you've paired down through your query modifiers so if you know you're going to be doing a lot of work that requires you to do things on the entire graph that may change the performance characteristics for you a lot.

I like it and would use it again but there are rough edges to work around still and it is young so know your use case and know the trade offs you're making.
