My Choice and Explanation
I would choose the Samsung Galaxy S21 Ultra 5G. While it's older, the sheer difference in performance and camera capabilities outweighs the benefits of the Xiaomi's faster charging and lighter design.
My reasoning is as follows:
- I prioritize performance: I frequently use my phone for resource-intensive tasks, like gaming and video editing, and the Exynos 2100 chip is significantly more powerful.
- I value a quality display: I enjoy watching videos and appreciate the sharper, brighter screen on the S21 Ultra.
- I use my camera extensively: I would like the flexibility of the telephoto lens, high-quality selfie camera, and 8k video recording offered by the Samsung. The DxoMark scores are also an indication of how much more capable the S21 ultra camera is.
- I want long-term use: The S21 Ultra is guaranteed to receive more operating system updates, making it a longer lasting purchase.
While the Xiaomi's faster charging and lighter design are attractive, they don't outweigh the areas where the S21 Ultra significantly excels for my personal use case. I am willing to deal with the slightly heavier design and slower charging in exchange for the superior performance, display, and camera capabilities. The higher cost is acceptable for the additional benefits.
For someone else who prioritizes convenience and budget, the Xiaomi Redmi Note 12 Pro 4G would make much more sense. My preference is based on my own specific needs and usage patterns.
