Also using IntellJ. But how is the landscape with the other IDE's these days - is NetBeans keeping up?

Unfortunate, because it had (has?) a great Swing and UML editor, built-in for free.
Maybe I'm wrong and it's awesome now, but I haven't used it for a while in favor of Eclipse, and now, IntelliJ. This graph illustrates the IDE popularity between Intellij and Netbeans. IntelliJ became preferred over Netbeans about mid 2014.

IMHO Netbeans was ahead of idea in many ways. But since they didn't buy commenteers to hype their product it's pretty much nowhere, at least I don't know anyone who uses it.
