performance will be better on the pro because it has less pixels to cope with
Battery life should be far better on the pro though. 4k + amoled + 10nm. Do battery test gsm!
To be honest, I like the Mate 10 better. It doesn't seem to have any compromises besides the lack of an AMOLED screen. 16:9 is better anyway. And it has the same 4000 mAh battery, which is great.
16:9 aspect ratio yields 81.7% screen to body ratio, while 18:9 aspect ratio yields 80% ratio??!!!!!!!!!!
What was the point of having 18:9 then? I thank Huawei for showing others that small bezels can be done in 16:9 ratio. And I scold them for removing headphone jack unnecessarily just for the sake of doing it.
