LENOVO or iBALL? Whose phone camera is better in quality?

I want to know whether LENOVO'S CAMERA IS BETTER or iBALL'S CAMERA IS BETTER?
e.g. Lenovo S820's camera is > or = or < iBall Andi5.5N2 Quadro's camera
(both 12MP)

Note: Specifications are nearly same.
But, my question is on camera quality/clarity, which varies from brand to brand even if both phones are 8MP( or both are 12MP).

Added (1). Rajiv Makhni reviews all kinds of phones on TV show Gadget guru india. Even quality comparison, but he specifically didn't review these two together.
My brother compared Xolo 8MP with Lenovo 8MP camera phone, he found Lenovos 8MP was much better than Xolos 8MP. Samsung Galaxy series 5Mp is better than most small brands 8MP. Thats where quality comes into picture.

I'm not aware of anyone who reviews the quality of phone cameras. But you should keep looking.
