I was in that position 5 years ago. I really tried - spent time learning keystrokes etc. What got me was the lack of integration and lack of basics. For example, Find Usages and Search were incredibly crap - which is a major problem when you've been brought onto a new project and you need to read and understand the code base. Perhaps things have improved since then. Ended up installing IntelliJ on the sly (advantage of a personal license!)
