My Choice

Based on my analysis, I would choose the Oppo Reno5 5G.

Reasoning:

While the Xiaomi Redmi 9T's longer battery life is appealing, the significant advantages of the Reno5 5G in terms of display quality (AMOLED, 90Hz, higher brightness), overall performance (Snapdragon 765G), significantly better main and selfie camera quality, and much faster 65W charging make it the superior choice for my needs as a regular user who appreciates a fluid and pleasant daily smartphone experience. I value quality in all areas of my usage. The superior display quality and overall performance will make the Reno5 5G much more enjoyable, while the fast charging can easily overcome any perceived battery disadvantages. The higher quality camera setup is also crucial for me. While the Redmi 9T has a longer battery, I do not need it to last an extremely long time, so I am okay with trading battery life for everything else.
