My Choice

If I were to choose between these two phones, I would choose the Xiaomi 12T Pro. While both phones have good aspects, the Xiaomi 12T Pro offers a significantly superior experience in most practical usage scenarios. The significantly better performance of the Snapdragon 8+ Gen 1, combined with the smoother 120Hz display, superior camera system, and much faster charging, makes it a far more capable and future-proof device. The weight is a considerable difference, but the benefits offered by the Xiaomi 12T Pro outweigh this trade-off, for me. Although I value portability and battery life, the capabilities of the camera, the display and the performance is something I use on a daily basis.

It is important to consider that this preference is aligned with a need for a phone that can perform under heavy use, and it values performance, camera quality and display quality over the weight and cost. If cost was a primary concern, I would go for a mid-range phone that has a better price-to-value ratio.
