My Choice and Why
If I were to choose between these two phones, I would select the Xiaomi Poco X3 Pro. While the Realme C51 offers a newer OS and a lighter build, the Poco X3 Pro’s superior performance, significantly better display, and more versatile camera system make it the more compelling option for my typical use case.

Additionally, the ability to record in 4K and have multiple camera lenses provides far more options and value for me, and the higher quality audio is an extra benefit. The older OS is not a big issue for me as long as the phone receives security updates.
Ultimately, the choice comes down to personal priorities.
