[Q] which has better camera Xolo q1010i, Micromax Yu Yureka, Xiaomi Redmi Note topic

Hello guys need a little help
in Xolo q1010i, Micromax Yu Yureka, Xiaomi Redmi Note [Dual Sim] which has better camera ??

Xolo Q1010i has 8MP Rear with Sony Exmor R Sensor with 5-element lens
Micromax Yu Yureka has 13 MP Rear Sony IMX135 CMOS Sensor with 5-element lens
Xiaomi Redmi Note has 13 MP Rear Q13S01B Sunny N1404 CMOS BSI Sensor without 5-element lens & comes with wide 28mm angle.

I understand the 5P lens produces better and finer picture quality and I noticed Sony's Exmor R Sensor works better at low light than Sony Exmor RS Sensor [given the fact that Exmor RS is a newer sensor compared to Exmor R].
It seems like even Redmi Note has a good camera with wider angle but probably is not upto the mark under low light condition compared to Exmor Sensors ??

Which phone has a better camera for taking pics among these 3 models ?
camera experts help :D
