Most of friends are good at Java recommended Eclipse to me as my main IDE for Java. There are a lot of plug-ins, such as spring IDE. But I still feel more comfortable to use NetBeans. Because I spent some time using Netbeans many may years ago. Morover, I felt NetBeans is more similar with Visual Studio, that seems to be more C# programmer Friendly. As a C# programmer, so I choose it. Besides, Netbeans support Spring MVC3 and Hibernate which are the frameworks I need to use. It can fulfill what I need. Thus, NetBeans is my choice!
