My Choice: Xiaomi 14

While the S23 Ultra offers a compelling package, I would choose the Xiaomi 14. The combination of the newer Snapdragon 8 Gen 3 chip, faster 90W charging, brighter display, and more compact form factor outweighs the S23 Ultra's advantages for my personal needs. I value portability and performance, and the Xiaomi 14 delivers in these areas without significant compromises in other aspects like camera quality. The price difference, while not explicitly quantified here due to variable pricing data, further reinforces the Xiaomi 14's value proposition. The S23 Ultra's superior zoom is tempting, but not crucial for my typical usage. Ultimately, the Xiaomi 14 better aligns with my priorities for a daily driver.
