My Choice
I would choose the Xiaomi Redmi Note 12S.
Here's why:
The difference in display technology is a major factor. AMOLED provides a much better viewing experience which is important for any user who uses their phone for any media consumption. The drastically improved processing power makes it a better phone to use for any task. The faster charging speed also saves time which makes the phone feel faster and more efficient in general use. The improved camera sensor, despite the slightly smaller aperture makes the image quality better which would also be a priority for many users. Finally, having stereo speakers and Hi-Res audio makes the user experience much more enjoyable for listening to music and watching videos.
The trade-offs of a slightly less accurate GPS and the lack of a proximity sensor are minimal compared to all the other advantages that the Redmi Note 12S has.
