My Choice

Personally, I would lean towards the Xiaomi 12X. While the Reno8 Pro is a strong contender, the slightly better screen protection, the inclusion of 8K video recording, enhanced video stabilization, and better audio features are significant advantages for my use cases. I also value the more compact design, making it more comfortable for me to carry and use one handed. The 13MP wide angle lens is a big advantage over the 5MP on the Oppo. While I appreciate the faster charging on the Oppo, the Xiaomi still charges quickly, and the other features make it a better fit for my personal preference. I can always carry around a charger with me if need be. It is a trade-off, but one I am willing to take.
