I'm an emacs fan. But when it comes to Java and big codebase (5+ developpers), JetBrain or Eclipse are just the way to go . They provide : code navigation and fast indexing (emacs LSP is just so slow), super integrated debugger, tons of predefined stuff to open common's file. They just more intelligence about your code packed in. With emacs it's all bare bones. So basically for me it's about big project == big IDE and everything else is emacs (which is a sizeable share !). Also, I'd say that Emacs makes my life much more pleasant too : the community, the license, the endless customization, the millions packages; that's part of my life too and the more "pro" IDE's just absolutely don't deliver on that side.
