My Choice

If I were choosing between these two, I would pick the Realme GT Master. While it's an older device and the missing size dimensions are frustrating, the sheer difference in performance, display quality, and camera capabilities makes it the better choice for my needs. I value a smooth and responsive user experience, and the Snapdragon 778G 5G chipset delivers that in spades. The AMOLED display is a huge plus, and the faster charging is incredibly convenient. Even though the Redmi A3 has a more recent version of Android and a slightly larger battery, those advantages don't outweigh the GT Master's superior performance and overall user experience.
