I bought the OnePlus One when it was released and it was and still is a great phone, however their price point now places their newer offerings with the Samsung S series and Nexus/Pixel devices. It doesn't have enough going for it to warrant paying those prices. If anything it taught me that phone brands I hadn't heard of could compete with the top line ranges. After my OnePlus I tried a bunch of Chinese brands and found Xiaomi to have the best combination of features and price in the market, plus due to their ubiquity they also get plenty of custom ROM options.
