Sony FDR AX1 vs Sony PXW Z150

I have enough money to buy either one of these cameras. I shoot still photography and event video. I also shoot interviews in studio and on location. I need a run and gun type camera that also works well in low light for Theatre and Dance.

I am hoping someone can help me decide between either of these or none of the above. Also I am upgrading from a Sony EX1 which works great except for low light.

Looking forward to hearing some opinions. Thanks
