Well programming is just programming, if you can do it in 1 language you can do it in another, I would just prefer to be able to do things in Unreal instead of Unity because I prefer working in Unreal and I can prototype things much faster in blueprints than I can doing it in C#. And since most of my work is just prototyping thats all I care about really. All the “blueprint” type plugins for Unity are quite annoying and not great to work with.
