The tooling is great, don't get me wrong. But as soon as you need to do anything that slightly deviates the norm in Unreal engine, you're constantly butted up against broken features, or terrible performance. I can't count the number of times we had to fix a feature or some silly performance problem that was broken in the engine itself.

The latest of which was Iris (to be fair, it is in an early state, but it is a major improvement to ue4's replication), there are some baffling design choices that deliberately made it way harder to make custom serializers for networking.

It's not all sunshine and rainbows. It mostly depends on if you walk the well trodden path or not.
