The main advantage of IntelliJ or any other IDE by JetBrains over Emacs, is that the out of box experience IDE provided, especially from a new programmer's perspective. All they need to do to click a button, check few checkbox, then IDE will resolve it for you and tell you what happened.
But to make Emacs do any complex behaviors, you usually have to write additional codes or configurations to glue different features together. Not to mention you need to read documents and debug it when there is an error. In JetBrains IDEs those are integrated already. A context-aware error detection and code inspection is available the second you open the IDE first time. That is something default Emacs can never do.
The main advantage on Emacs over IDEs, is that you can ask Emacs to do whatever you want as long as you know how to implement it. Practically speaking, you most likely will accumulate many little functions over time that is specific designed for your workflows. That kind of customizability is something IDEs cannot provide. I do not consider myself an Emacs power user, but I still benefit form it.
Emacs is also have better text editing features in general. You can use the same features no matter what text file you are editing. That's why people want to use Emacs for everything.
In short, they are different tools, use it where it is suitable for you.
For me, I whine about how bad the editor is when I use IDE, then I complain about how bad the integration my Emacs has between multiple tools (mainly my inability to make it work).
Hope this give you some ideas.

For example, I made a lot of scripts in Python to refactor codebases by automatically splitting files (including imports). Could I do that with emacs? Probably yes. But why?
For most intents and purposes it doesn't matter if your "automated editing" environment is integrated in your editor.
