Wait, graph-tool is finally on Python 3? I loved graph-tool. Even did a conference talk on it once. But for years it was Python 2.7 only, so much that I finally gave up on ever using it again.

For me, NetworkX is good for exploration, but shouldn't be used for anything serious in production. Once you sorta figure out what you want to do there are so many other things you should use before NetworkX that may take longer to get the data in, and may be more annoying to query, but are ultimately more suited to the task.

It's hard to even compare these different tools directly because they solve different problems. For example, if data integrity was paramount I'd just use Postgres and recursive querying / intelligent partitioning. If speed were important, Memgraph or sparse matrices in Numpy. If the data were large documents with tag like relationships, some sort of document store (used Riak last time around, but that was over ten years ago).
