Wrapping things up, were left with the question of the Nexus 6P is a worthwhile buy or not. Here Id like to offer two conclusions, one for US users and one for buyers in Europe and the rest of the world. At a US price starting at $499 for an unlocked variant, it seems that the Nexus 6P hits a sweet-spot in terms of price-performance and is able to position itself very competitively against other devices. Googles own services are also much more prevalent and far reaching in North America, so theres definitely advantage of having a pure Nexus experience (Along with the non-carrier firmware advantage). Here the Nexus 6P is definitely a worthwhile purchase.
For regions outside of North America, and Europe especially, the Nexus 6P just seems an unreasonable device. Starting at prices from 649, you would expect a device without drawbacks, and its simply not worth the premium over other devices, or at the same price youll be better off with an equally priced S6 Edge+ or Note 5 if its available in your region. Here, the Nexus 6P just simply doesnt seem that attractive unless youre putting a lot of weight into the Google Nexus experience, which I find to be a rather subjective aspect of the device. With Snapdragon 820 phones coming in just a few months theres also the viable option to hold out for better alternatives as we're on the verge of a large generational jump that will undoubtedly bring a lot of improvements to the table.
