My Choice
I would choose the Xiaomi 13 Ultra. While significantly more expensive, it offers a vastly superior experience in almost every aspect. The performance, display, and camera system are all top-of-the-line, making it a true flagship device. The Redmi A3, while affordable, is too compromised in terms of performance and features for my needs. I prioritize a smooth and responsive user experience, high-quality visuals, and a capable camera, all of which the 13 Ultra delivers. The price difference is significant, but the value proposition of the 13 Ultra, for my use case, justifies the cost.
