What will be a better IDE for a beginner,Netbeans or Intellij?

Hi i was just wondering which IDE should i use for writing java programs.I used to write programs in Bluej while i was in school.I am thinking of upgrading my programming career and so need a bit of advice.I have heard that most developers use Intellij but i am also sure that Netbeans would help me to understand my program in a more efficient manner.So which one should i use?

Any help or suggestions?
