Netbeans was really great, maybe still is, but the noise jetbrains made with the astroturfing advertizing has jetbrains dominating everything.
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.
I'm someone who has regularly recommends Jetbrains software (including IntelliJ and Resharper) to others in comments, and now I'm wondering if they forgot to send me my check.
