There are many other advantages like out of the box support for a lot of common use cases like refactoring, navigation, build tool support, reuse common shortcuts like Control-C Control-V for copy-paste etc.
I would definitely advice new engineers coming into languages like Java to pick up an IDE like Intellij instead of vim.
I like how you can use command keys to quickly toggle on and off the project file and current-file's-components browsers, leaving the "distraction free" * editor window for much of your work.
* yeah, there's a mode with this name that auto-wacks ALL the supplemental panels, AND the window frame. I don't usually go that far, but it does show that they "get it" as far as what many of us IDE resisters disliked.
