My Choice

If I were to choose, I would personally lean towards the Xiaomi Redmi 9T. While the Realme C51 offers a few compelling features like the 90Hz refresh rate and faster charging, I find the Redmi 9T's strengths to be more significant for my personal use case. The higher resolution display is a big plus for media consumption, and the significantly larger battery would mean I wouldn't have to worry about running out of power during my day. The inclusion of a wide-angle lens is also a key point for me.

While the Realme C51's chipset might benchmark slightly better, I believe the difference in day-to-day use for typical tasks would be negligible. The Xiaomi Redmi 9T also has more practical features with the reverse charging function, screen protection and its enhanced audio quality. The superior camera system with multiple sensors also gives it a clear advantage for photography.

Although I appreciate the faster charging of the Realme C51, the substantial battery advantage and overall utility of the Xiaomi Redmi 9T make it the more compelling choice for my specific needs.
