It depends on what you want to do. If you want to party hard and like the rat race and concrete jungle of Waikiki, you need to spend your time on Oahu. If you want laid back so far you fall over backwards and want to see the most beautiful parts of Hawaii, go to Maui, Big Island, Molokai or Kauai. I'll gladly supply you with any info I can if you tell me what your interests might be.
