My Choice

I would choose the Xiaomi 12X. While the Oppo Reno5 5G has a slightly larger screen and reverse charging, the Xiaomi 12X offers a substantially better overall experience due to its significantly superior performance, smoother and brighter display, better camera features and better screen protection. As a user who appreciates responsiveness and smooth gaming performance, the difference in chipset and refresh rate is critical. Additionally, the enhanced camera capabilities of the Xiaomi 12X make it the better choice for capturing photos and videos in a wider variety of scenarios. While reverse charging is a nice to have, its not as critical as better performance or camera results for me.
