Cons
Con Bland UI
The UI is fairly boring and has limited customization options. There is a dark theme available; however it only applies to the editor. The surrounding windows and borders remain light. You can see a collection of screenshots here.
Con Is not free
But it does have a free version (Community Edition).
Con Heavy
Consumes more resources than VSCode etc. But depending on your use-case, it can still be worth it for the benefits you get with this editor.
Con Autocomplete does not work while IntelliJ is indexing
But this, in general, is not much of an issue. Usually after npm install, etc.
