I used IntelliJ for almost two years, JS and Java. I hope I never have to use it again. It's laggy, clunky and with a less than intuitive UI. Yes, it is powerful but it doesn't weigh up for its shortcomings.
I work on an enterprise project with 100+ gradle projects and a pile of targets for docker containers, kubernetes deployments, DB schemas, Redis stuff, etc..
Eclipse is incredibly slow in this use case compared to IntelliJ and would frequently gobble 10GB of Ram. I switched from Eclipse to IntelliJ earlier this year after years on this project and IntelliJ is amazingly better.
But if you're using some different build system and a different type of project configuration maybe it's the other way around..
I think the thing with these
This was back in 2011 though. Obviously things have changed.
The difference between Eclipse and IntelliJ was like night-and-day, however, in terms of performance.
I don't love eclipse, not a person to get too attached to an IDE, but it is an incredible piece of open source software. It works.
Also too much effort in rewiring keyboard shortcuts that have made their way to my muscle memory. So eclipse it is.
