I agree these are some of the best pics I have seen from a camera phone bar none - especially in regards to natural appearing images and color. It is nice to see an objective Note 4 owner in the Nexus 6 forum as there are three people dominating all of the threads on a mission to discredit the Nexus 6 and promote the Note 4 to prospective buyers of such ( you would think Samsung was actually paying them or something )...
Note 4 is a great device as well and the main attraction to me for the Nexus 6 are these pics, Motorola brand, and the extra 9.3% of screen real estate...
It all comes down to what your priorities are - you can't go wrong with either one...
