My Choice: Xiaomi 13T

While lacking specific pricing information, the Xiaomi 13T offers a significantly superior user experience due to its vastly improved display, performance, and video recording capabilities. The difference in resolution alone makes the 13T a far more compelling device for everyday use. Even if the Realme 12x is cheaper, the performance and display advantages of the 13T are worth the likely price premium for most users. The 12x seems positioned as a more basic, budget-friendly option with compromises in key areas that significantly impact daily usage. The superior hardware of the Xiaomi 13T will likely age better, providing a smoother experience for longer.
