My Choice: Xiaomi Redmi Note 12 Pro

If I were choosing between these two, I'd go for the Redmi Note 12 Pro. While the A3x offers excellent value for its price, I prioritize a smooth and responsive user experience, a vibrant display, and a capable camera. The Note 12 Pro delivers on all these fronts. The performance difference between the Dimensity 1080 and the Unisoc T603 is substantial, and the AMOLED display is a major upgrade over the A3x's IPS LCD. I'm willing to invest a bit more for a significantly enhanced overall experience. While the longer Android update support on the A3x is tempting, the superior hardware and user experience of the Note 12 Pro outweigh that benefit for me.
