What I would choose and why!

I would choose the OnePlus 9R

While the Xiaomi Poco M3 has a significant advantage in battery capacity, the overall experience of the OnePlus 9R is far superior. The difference in performance is night and day, the 120Hz AMOLED display is a huge step up, and the camera system is significantly more versatile. The 65W fast charging on the 9R also helps mitigate the smaller battery capacity. For me, the smoother, faster experience and the quality of the display and camera outweighs the slightly lower battery life. I am not a heavy gamer, but I do consume media and use my phone a lot, so the AMOLED screen would be a massive advantage for my use cases.
