Interesting. I'm considering exactly these three phones. I've been an iPhone user since the very beginning, so I really want to like the 6s Plus - but it's hard for me to get excited about the hardware, especially the display (Smaller 5.5" low-res LCD screen) and the size/weight. It's unnecessarily huge (as is the 6P - Samsung really nailed design with the S6 & Note 5 this year). It's just not a good design for the price when you compare it to Android hardware at the moment. I've always felt the Apple premium was worth it because you received unquestionably superior hardware - but with the 6s Plus you are getting an inferior display in a large heavy package. 3D Touch is still a gimmick for contextual menus. The 6s processor performance and battery life are very nice though and I still much prefer iOS over Android.
With the Nexus 6P, I'm concerned over the bare-bones stock approach - especially after coming from an iPhone, as well as the screen brightness. I also don't like the rear fingerprint sensor. At least it packs a higher-res AMOLED display into something the same size as the iPhone 6S Plus while weighing less and costing about $350 less.
The Moto X Style/Pure Edition is the wild card. It's quite a bit less than an iPhone 6S Plus ($650 less right now in the US), yet it still packs a 5.7" Quad HD display (LCD rather than AMOLED) which is better than the iPhone, all while having a better screen-body ratio and lower weight. Performance may not be the absolute best, but I'm not sure it matters for me. It's drawbacks are lack of a fingerprint sensor, it's somewhat ugly design (in my opinion - at least compared to the other two), and it's thickness. I've also read that it has poor battery life. While it's not the best overall phone, I'm trying to decide whether it would be best to go with this to tide me over to the iPhone 7 with hopefully a much improved screen & better, smaller design (assuming it has a headphone jack - if not, that's another killer).
How do you compare the Moto X screen to the iPhone 6S? Does the thickness bother you coming from the other two devices? Also, what kind of battery life are you getting?
The iPhone may have a lower resolution but honestly I don't notice much of a difference resolution wise between any of the devices I've had this year and I've had many QHD devices.
What's more important are things like viewing angles, colour shift, brightness, outdoor visibility etc..
The Moto X Style has a very good screen, whilst there is a small amount of shift in off angle viewing compared to the others it's very mild. Not as pronounced as some reviews highlighted.
The colour accuracy is good and there is a more accurate colour mode buried in display settings.
The Moto X Style/Pure for its price point is an excellent phone although
1. It has a very high memory usage compared to Nexus 6P - even compared to the Moto X 2014. Not sure why the device will sit close to 2gb used on boot whilst the 6P will be just over half of that.
2. The hexacore 808 is less efficient than octacore of the 810 in the 6P. The 808 gets warm very quickly in fact the Moto X Style/Pure always has a generally warm feel to it even just in your pocket. The blackberry priv suffered same complaint with its 808. Yet the 6P rarely gets warm.
3. The Moto X Style / Pure has small moments of stutter, lag - likely due to the high memory issue. I thought marshmallow would fix this but it's still there compared to the 6P
4. Battery life isn't as good and it's probably related to issue 2 as mentioned above.
5. However the 20mp camera I am surprisingly very happy with this year.
It's a great phone for its price but with concessions. It's whether those concessions are worth paying an extra $100-120 for the 6P instead or an extra $400-500 for a 6S+
