The OnePlus 3 Review
So it's "scores" actually went down pretty significantly with the findings in this review BUT, other than the display (which really tanked it), it's better than the OP2 in just about every way.
Camera was a weird category. It wasn't doing well with saturation accuracy but was taking much sharper low light photos than the Nexus 5X. It was beating the iPhones out on just about everything, which makes it a top 10 camera, very likely in the Nexus 6P or possibly even LG G5 range.
Overall, very good phone at a low price = good value, and it's right about dead on par with the Moto X Style, which is the same pricepoint, so very appropriate.
All of that said, the USER hands on feedback of this device has been very positive, so it's quite possible that OnePlus finally put out a total device experience that's better than the sum of it's components.
