Personal Choice
If I had to pick, I would choose the Asus Zenfone 9.
Why? The Zenfone 9 is a powerful, feature-packed device that doesn't compromise on key aspects like performance, display quality, and camera capabilities. As a tech journalist, I use my phone for a variety of tasks, from capturing images and videos to writing articles and testing software. The Zenfone 9 offers the performance and features I need to do this efficiently, and its compact size makes it easy to carry around all day. Although I would need to carry a power bank to get through a long day of usage, the drastically improved performance is well worth it. The premium build and feel also add to the positive experience of using the device. While it is certainly more expensive than the Redmi A3x, I believe the added capabilities justify the higher price.
The Redmi A3x, while newer, simply can't compete with the Zenfone 9 in the areas that matter to me most. It is a budget phone designed for light usage, and it has made too many trade-offs to be my primary device.
