Here is my 2 cent: Java developer for about 10 years. CLI is always good to know, Vim, Emacs learn them if you like them. But if you want power and easy overview of large collaborative projects with a lot of code, which mostly working at medium to large companies is all about, you should use an IDE. I didn't have a choice at some places, they just said: "we use IDE x here". Learning Jetbrains IDEA took me a while though but today I love it. If you're only coding small projects for yourself you don't need an IDE but I use an IDE in those cases too.
