What I would choose and why:

If I were choosing between these two phones, I would pick the OnePlus 9 Pro. While it's undeniable that the Redmi 10 is a more budget-friendly option with a larger battery, the sheer difference in performance and overall user experience offered by the OnePlus 9 Pro is too significant to ignore, especially since I prioritize performance and camera quality.

The OnePlus 9 Pro's powerful Snapdragon 888 chipset, coupled with its much smoother 120Hz display, higher resolution, and much higher outdoor brightness, would provide a significantly more enjoyable and responsive experience for daily use and gaming. Additionally, the superior camera system, which includes a telephoto lens, larger sensors, and 8K video capabilities, would allow me to capture better quality photos and videos. While the faster charging speed of the OnePlus is also a big plus.

For me, the significantly enhanced performance, superior camera capabilities, better display, fast charging, and better build quality far outweigh the benefit of a larger battery and the lower cost offered by the Redmi 10. While the Redmi 10 would be a decent device for someone on a tight budget who only needs basic smartphone functionality, the OnePlus 9 Pro provides a high-end experience that is worth the extra cost.
