My Choice and Why
If it were my money, I'd choose the Xiaomi Redmi Note 12 without a second thought. The difference in display quality alone (AMOLED vs IPS LCD, higher resolution, higher refresh rate) is worth the added cost. The performance leap from the Snapdragon 4 Gen 1 is substantial, ensuring that the phone can handle daily tasks and even some light gaming without breaking a sweat. The camera system on the Note 12 is also miles better, providing more detail and options. The faster charging is a nice bonus, too. While the A3x is a newer phone, it's clear that it has made significant compromises to achieve its price point. While the Note 12 might be more expensive, its more robust features make it a better investment over time. The difference in overall experience between the two is substantial and would make it a far better device for my day-to-day needs.
