My Choice

If budget wasn't a concern, I would choose the Xiaomi 13 Ultra. Here's why:

  • Camera Capabilities: As someone who enjoys photography, the significantly superior camera system is the biggest draw. The larger sensor, multiple lens options (especially the telephoto), and advanced features like 8K video recording make it a much more versatile and capable tool for capturing high-quality images and videos. The higher DxOMark score reflects this advantage in real-world performance.
  • Performance: While the OnePlus 8T is still capable, the Snapdragon 8 Gen 2 in the Xiaomi 13 Ultra offers a noticeable boost in performance. This translates to smoother multitasking, faster app loading times, and a better overall user experience, especially when running demanding applications or playing graphically intensive games.
  • Display: The higher resolution and brightness of the Xiaomi 13 Ultra's display are significant advantages. The sharper image quality is noticeable when viewing photos and videos, and the higher brightness makes the phone much more usable in bright sunlight.
  • Battery Life and Charging: The larger battery and faster charging speeds of the Xiaomi 13 Ultra are also appealing. Longer battery life means less frequent charging, and the fast charging capabilities mean less time tethered to a power outlet.
  • Build Quality: The upgraded Gorilla Glass Victus 2 is a nice addition.
