My Choice

If I had to choose between these two phones, I would pick the Oppo Reno5 5G. While the Xiaomi Redmi Note 9T has a bigger battery and slightly better benchmarks, the Reno5 5G's superior AMOLED display with a 90Hz refresh rate, faster charging (65W is a game-changer), more versatile camera, more RAM/storage, and a more modern Android version make it the more compelling option for me. I prioritize a great visual experience and speedy performance, and the Reno5 5G delivers that without needing to be plugged in every few hours. The enhanced camera features are also a big draw, allowing me to take higher quality pictures and videos without needing to carry a separate device. Despite the lower battery capacity, the quick charging negates that downside and having double the RAM/storage makes it the more logical option in the long run.
