Note 4 takes better pics. JR must be crazy to think the N6 takes the better overall shots. But I will say that it is close in many instances and it doesn't sway me away from getting the Nexus 6.
I agree that in the one low light shot that the note 4 is definitely better but the sony sensor in the nexus 6 is very capable so we may see some improvement here. It is interesting that even though the Nexus 6 has less pixels the pics tend to have more detail. In the brighter scenes the note 4 pics are definitely washed out a bit. Whether you like the note 4 or nexus 6 pics better they are both in the same ball park.
