My Choice

I would choose the Samsung Galaxy M55.

Reasons:

While the Xiaomi Redmi 9T's larger battery is tempting, the overall user experience offered by the Samsung Galaxy M55 is far superior. The much faster processor, better display with a 120Hz refresh rate, significantly improved camera system with OIS, EIS, higher video resolution, faster charging, and the newer version of Android make it the more compelling option. The additional sensors in the M55 further enhance the user experience for more demanding users.

The M55 provides a smoother, more enjoyable experience in everyday use, and its superior camera makes it better for capturing photos and videos. The slightly smaller battery capacity is a compromise I'm willing to make for the other significant upgrades offered by the Galaxy M55. The faster charging helps mitigate the difference in battery capacity.

For me, the performance boost, display quality, and improved camera are worth the extra cost, making the Samsung Galaxy M55 the better choice. The Redmi 9T is a decent budget option, but the M55 is just on a different level and more future-proof.
