If Unreal got proper scripting language support, I'd seriously consider giving it another go. I'd rather they go the Unity approach than the Godot approach and use a real-world language (C# is used outside Unity of course, GDScript is only used in Godot, though it does have bindings), but I'll take what I can get, clearly as I use Godot rather than Unity.
As it stands, picking up blueprints feels like I have to learn a whole new system which will go to waste if I decide not to stick with Unreal, and C++ seems like it'd be a pain to work with.
Edit: Forgot Godot had C# support. It still doesn't feel as "first-class" as GDScript, but its certainly more closely integrated than bindings, so maybe something to consider. Also, whilst I generally prefer a single language being tied to a single tool (trying to learn Raylib taught me this, where every example you find is in a different language), its nice knowing I can use C# without being locked into Microsoft
