If your organization works with developing or supporting Java applications and is focused on running efficiently with a lean budget, NetBeans would be a good choice to consider.
If your development staff uses other languages, or prefers a high level of available professional IDE support, it may be better to consider a paid option if your budget allows.
Netbeans enhances my coding work, shows me where I have errors and helps find variable instances. I would be lost without find/replace in projects functionality as I use projects as templates for new projects. Occasionally the code hints aggravate me, but I understand that it is actually making me a better coder, working to get the 'green light' of a clean file with no errors or clumsy code.
NetBeans has a very strong user community. We can find solutions here for almost all the problems we face. In addition, we can forward NetBeans Support teams the problems we cannot solve. We can get quick feedback from the support teams, but I generally try to solve my problems by following the forums.
IBM Rational Application Developer and IntelliJ IDEA are great with hell lot of features packed into the product and are subscription based. However, most of the features they were providing were moot from my organization's business perspective and the cost was expensive. Eclipse is an opensource product with great features, but is difficult to configure and use as compared to NetBeans. One of the frustrating issues we faced with Eclipse was its slowness while saving a file. http://https//stackoverflow.com/questions/40166270/eclipse-neon-pathetically-slow
