Netbeans is great, it has changed a lot since the old days around 2002, where it was quite slow and one even had to mount filesystems into the workspace.

The Netbeans rewrite that followed, the use of Ant and Maven as project files and the overall plugin quality beats Eclipse any day.

The HTML5 support is great, specially the integration with JavaScript frameworks and static analyzers.

I also enjoy the C++ and Assembly support is also quite good, given it is the official Solaris IDE.

Best of all, no nonsense workspace or perspective modes in sight.

And the plugins API is quite good.

"...the use of Ant and Maven as project files..."

This is what I want most from a Java IDE. I find IDEs project configuration complex, arbitrary, inscrutable, and un-diffable (making version control on the project files mostly useless).

Eclipse and IntelliJ make some effort to work with Maven and Ant, but tend to get out of sync in hard to debug ways.

Android Studio (Google's fork of IDEA) was awful at the beginning but is on the right track to getting quite good with Gradle.
