My Choice

If I were choosing, I would absolutely go for the Asus Zenfone 9. The gap in performance is enormous; the Snapdragon 8+ Gen 1 absolutely blows the MediaTek Helio G85 out of the water. This isn't just about benchmarks; it's about the everyday experience. Apps launch faster, multitasking is smoother, and gaming is far more enjoyable. The display is also dramatically superior; the AMOLED panel with its 120Hz refresh rate is a joy to use, providing vibrant colors and smooth scrolling that the Redmi's LCD simply can't match. Also, as a photographer, the superior camera capabilities, with the stabilization and higher video quality are a big draw. Yes, the Zenfone 9 is pricier, but for me, the performance, display, and camera are well worth the investment. The compact size also means it is a lot easier to use one-handed.
