Showcast or AT2

Hi, I just wanted your opinion as to which you prefer out of Showcast and AT2? I think showcast is sydney based and AT2 is melbourne based and Showcast is more for movies and AT2 is more for australian TVS. Is that right? I've been with my agent for 2 years, the first i was subscribed to showcast and this year to AT2. I found i had more professional auditions when i was with showcast - BUT- who's to say they were through showcast or my agent... hmmm...
