My Choice
I would choose the OnePlus 9 Pro. My preference is for a device that offers a superior user experience, particularly in terms of display quality, performance, and camera capabilities. While the Xiaomi Redmi 12C has a larger battery and is more affordable, the trade-offs in other areas, especially performance and screen quality, are too significant for me. The enhanced display of the OnePlus 9 Pro alone makes the experience much more pleasurable, and the powerful chipset and versatile camera make it a more enjoyable and effective device. Even though the battery is smaller, the 65W charging means it wouldn't hinder daily usage for long. The advanced features, like reverse wireless charging, and the better audio also help justify the higher price point.
