  • More RAM: The option to chose between 4, 6 and 8 GB of RAM provides better multitasking and future proofing.

While the Redmi A3x has a slightly larger and smoother display and a newer OS, these advantages do not outweigh the significant performance and display benefits that the Realme 8 offers, thus making the Realme 8 a better choice in my opinion.
