I absolutely love the blueprint editor in UE4. It enables me to rapidly hammer out ideas and test new things. Not only that, but it helped me learn a lot about how to go about doing things in UE4 so when I started writing CPP I already had an understanding for where to put what and how to do it.
Easily the first visual programming language I used that actually sold me on the idea. Most of my experiences have been with systems that claim visual programming, but then require you to jump top code almost immediately. UE4 blueprints are sufficient to create the majority of a game.
