The Nexus 6P is way better Smartphone than 5X than any aspect, be it User experience, Processing speed, Display, Camera and all over the specifications one can draw 6P as a clear winner. The year 2015 has produced some of the best phones over the history of smartphone timeline, and 6P is no different from Google. 6P does have the caliber to beat the best on performance and camera. But I also, do feel the phone is a bit overpriced in the 600$-650$ range. Being an Indian, its not a market for masses to buy 6P, but 5X is. Nexus 5X, which is priced in the 330$ to 400$ is worth the price to be. While the 6P stand tall for specifications and design, the 5X stand for one of the best budget phones under just 400$.
Also, LG's customer service and after sales in India is quite good than that of Huawei. Thus I would love to own a Nexus 5X, for its price
Thanks !!
