My Choice

If I were choosing between these two phones, I would choose the Xiaomi Redmi Note 13 Pro+. While the Oppo A54 5G is a perfectly adequate phone for basic use, the Xiaomi offers a vastly superior experience in almost every aspect that I value in a phone: display quality, performance, camera capabilities, and charging speed. The AMOLED screen alone is a massive upgrade, and the performance boost makes the phone feel much more responsive and capable. Although the Oppo offers dedicated creative lenses, which may be useful for some people, the Xiaomi offers better image quality on the main lens, plus OIS, which is something I would value over the extra lenses. The incredibly fast charging would also be a game-changer for me. For my needs, the higher price is justified by the significant improvements in key areas.
