My Choice

If I were to choose between these two devices, I would choose the Asus Zenfone 8. While the Xiaomi Poco M3 Pro 5G offers a larger battery and reverse charging, these benefits do not outweigh the significant advantages of the Asus Zenfone 8 in areas that I value more. My priorities lean toward superior performance, a higher quality display, and a more advanced camera system, all of which the Zenfone 8 provides. The compact form factor of the Zenfone 8 is also preferable to me for better usability in day to day life. While the battery might not be as large, the faster charging means I am less likely to have to wait for it to be usable again. Ultimately, for me, the Asus Zenfone 8 offers a more compelling and versatile experience.
