My Choice: Xiaomi Redmi Note 9T
Given the significant performance advantage, superior display, significantly better camera system, enhanced audio, and faster charging, I would choose the Xiaomi Redmi Note 9T. Despite being an older phone and on an older OS, the Note 9T provides a much more compelling user experience across almost all major categories. The newer Bluetooth, better screen protection, and additional sensors also add to its appeal. It offers a much better long term value for anyone wanting to do more than just basic tasks on their phone, and is a more versatile device compared to the Redmi A3x.
The A3x has some benefits, most notably the newer operating system and marginally smoother screen, but its downsides outweigh its benefits. Its slower processing speed and lower-quality camera mean I'd be frustrated with its usage.
