Sorry pal, I don't want to waste my recourses for that Already I used IntelliJ Idea. That's why ask that question from you
I see. But i did not use IntelliJ IDEA for long time.

So i can not tell you its advantages compared to IntelliJ IDEA. But i guess, J2EE and J2ME support of Netbeans should be better than IntelliJ IDEA's. And the most important thing is the recent acceleration of Sun's support on Netbeans.
