My Choice and Explanation:

I would choose the Xiaomi Poco X3 Pro. Here’s why:

While the Redmi 10A is more budget-friendly and lighter, the X3 Pro offers a drastically superior user experience for a moderate price increase. The X3 Pro's performance, driven by the Snapdragon 860 chipset, ensures smooth operation, even with demanding tasks and games. The 120Hz display is a game changer for everyday use, making everything feel fluid. The enhanced camera system, complete with a wide-angle lens and high-quality video recording, is a huge advantage. The stereo speakers and better build quality are important for media consumption and durability.

For me, the price difference is justified by the significantly improved performance, camera system, and overall user experience. While the 10A would be perfectly adequate for basic tasks, the X3 Pro provides a more satisfying experience for a power user, and the better performance makes it much more future proof.
