My Choice

I would choose the Xiaomi Redmi 9T. While the 90Hz refresh rate of the Samsung Galaxy M12 is nice, I value the significantly better display resolution and sharpness of the Redmi 9T. The improved performance from the Snapdragon chipset is also a major plus, making the overall experience much more fluid. Additionally, the considerably larger battery capacity ensures I won't have to worry about charging as often. The better camera, especially for low-light shots, and faster charging are just icing on the cake. For me, the trade-off in smoothness is worth it for overall better usage in my usual scenarios, where I need to load apps and multi-task, plus consume media. The Hi-Res audio is also a major plus.
