The very first row of the rear mezzanine is still the tenth or twelfth row of the mezzanine. Your seats aren't raked high enough to see the front of the stage over the edge of the mezzanine and the overhang of the gallery blocks your view of the top of the stage.
I've never been in the orchestra at City Center, but I'd go with front row of the gallery. Even if it's all the way on the side, you get a great view from up there, and no one's blocking your view.
