My Personal Choice

If I were choosing between these two phones, I would pick the Asus Zenfone 9. While the Redmi Note 13 Pro+ has some compelling advantages, like its larger, brighter screen, higher resolution main camera, and fast charging, I value the Zenfone 9’s combination of small form-factor and powerful performance for gaming, great audio quality, and advanced video recording features. I often find myself needing to use my phone one-handed, and the Zenfone 9’s compact size would make it more comfortable for everyday use, and I also enjoy the audio features on a high level.
