I dont agree when you say the Nexus offers a more fresh experience. I got Marshmallow on my X Style more than 10 days ago, same animations, same OS. But with those smart functions Motorola added to the stock version of Android. And Motorola is one of the fastest brands when it comes to updates.
I think Google missed the point here , 2015 has shown us that we can have affordable android phones with great builds, top if the line specs and good displays. Google really missed all of those marks with the 5x.
