The reason why I stayed with VIM as my editor is that it's very efficient at doing repetitive tasks that otherwise would block my thoughts for a long while. When you are refactoring a codebase, when you need to rename things inside a block, when you need to match function signatures, when you need to change a bunch of statements or expressions inside a block ... that's where VIM and emacs shine. Additionally I'd recommend to learn about fuzzing and the ideas behind it, because it teaches you to write more defensive code and will teach you to never use these "quick return" style branches ever again.
