My Choice

I would choose the Xiaomi Poco F5. While the OnePlus 9 Pro has a fantastic display and a more versatile camera system on paper, my primary use case is a combination of daily tasks, some gaming, and media consumption. The Poco F5's lighter build, more efficient processor, longer battery life, and more comfortable design would have a greater positive impact on my daily experience. Also, the more up-to-date OS and higher raw performance from the chipset would be important to me in the long-term. While I would be sacrificing some camera quality and display clarity, the Poco F5 has a good enough display for most use cases, and the primary sensor is still very capable, especially when considering the price point. It is for these reasons, that I would choose the Xiaomi Poco F5.
