My Choice and Why

If I were choosing between these two phones, I would choose the OnePlus 9 Pro. While the Xiaomi Poco F4 offers compelling value, the OnePlus 9 Pro's overall package aligns more closely with my priorities. The superior camera system—including the telephoto lens for optical zoom, high-resolution ultrawide camera, a black & white lens, and its advanced video recording capabilities—is very appealing, I also value the convenience of wireless charging, the higher resolution screen, and the slightly better performance it offers. Even though it is older, it receives an update to Android 14. While the price is a factor, the benefits offered by the OnePlus 9 Pro would be worth it for me personally, even though the Xiaomi Poco F4 would be more than enough for most users.
