What I would choose and why!

Personally, I would go with the Xiaomi Redmi 10. While the Oppo A55 has its strengths (better performance in benchmarks, more RAM, better Bluetooth audio codecs, and better location tracking) the Redmi 10 offers a more well-rounded package for everyday use. The significantly better display with its 90Hz refresh rate, the more versatile and capable main camera, the faster charging, and the inclusion of stereo speakers all tip the scales in its favor. For me, a sharper screen and improved camera experience make a bigger difference in daily use than a marginal performance gain and a few extra features. I also value the screen protection provided by Corning Gorilla Glass 3. If you are not fussy about the display or camera, then the Oppo A55 may be a better option for you, but for the casual user, the Redmi 10 is simply the better option.
