My Choice
If I were choosing between these two phones, I would unequivocally choose the Xiaomi Redmi Note 9T. While I acknowledge the Redmi 10A is newer and potentially cheaper, the performance disparity between the two is too significant to ignore. As someone who uses their phone for a variety of tasks, I need a device that can handle multitasking, and the Note 9T does that with a more powerful chipset. Additionally, the higher resolution display, the superior camera, the faster charging, and the better audio experience, make the Redmi Note 9T the better choice. The Note 9T offers an overall superior user experience that justifies spending more. The 10A is suitable for those who just need a basic phone, but for a modern user, the 9T would be the far better device to use every day.
