What I Would Choose and Why

I would choose the OnePlus 9. While the Xiaomi Mi 10T 5G has its merits, the OnePlus 9 provides a more well-rounded and premium experience. The superior AMOLED display is a major factor for me, as I consume a lot of media on my phone. The faster performance of the Snapdragon 888 ensures a smooth experience with demanding apps and games. Additionally, the improved camera system, especially the ultrawide lens, is a significant upgrade. Although the battery is slightly smaller, the 65W fast charging and wireless charging capabilities mitigate this concern.
