Last week I was working with Eclipse and once again it helped me realize why I love IDEA much better than other Java IDEs around. It's still the best IDE around, period. However, I believe that recent versions of IDEA are not as throughly tested as before. Also some of the UI changes are not well thought of (e.g. have a look this bug report I submitted last night: http://youtrack.jetbrains.net/issue/IDEA-53738?query=by%3A+behrangsa.)
I believe that it is necessary for IDEA developers to devote more time to fix the outstanding IDEA issues rather than adding new features to the IDE. A quick look at the issue tracker shows that IDEA has more than 6000 open issues.
Finally, something I like about NetBeans is that, unlike Eclipse and JetBrains, they release minor versions very frequently. Please release stable bug fix versions more frequently! IDEA is also missing an incremental built-in updater.
