Unreal has Blueprints that are superior to all Unity's visual scripting solutions, so if you're a beginning indie dev, you don't need to write code at all. If, however, you're a professional game developer who tries to get his game to run 60 FPS on a 6-year old phone (not a hypothetical example, I've led a project that had 60 FPS on iPhone 4 in 2016 with Unity), then you WANT the C++ and engine source code. I've been working with Unity since 2009 and hope to never touch that giant flaming pile of shit again in my life. Having moved to frontend development still, I'm very happy to work with tools that mostly work, and if they don't, you can actually dig in and debug them, with healthy development culture that actually encourages you to do so. Sorry for the emotional rant; 10 years of Unity experience (not really though, I've done other things in this time as well) do that to a person.
