My Choice and Why

If I were choosing between these two devices, I'd go with the Sony Xperia 1 III. Here's why:

As a tech journalist and analyst with a strong engineering background, I prioritize performance and cutting-edge features. The Xperia 1 III's OLED display, the powerful Snapdragon 888 chipset, and the high-end camera system are compelling. For me, the ability to have a rich media experience, game with smooth graphics, and capture high-quality content is what matters.

Yes, the Xiaomi Redmi A3x is more budget-friendly and offers a bigger battery, but the trade-offs in performance, display, and camera are too significant. I'd be okay with the Xperia 1 III's smaller battery given that I have multiple chargers at my disposal. For me, the technology and superior features of the Xperia 1 III outweigh the benefits of a bigger battery and a lower price.

Ultimately, the choice between these phones comes down to your priorities. However, if you have the budget and a tech enthusiast who appreciates cutting-edge features and performance, the Sony is the way to go.
