My Choice

If I had to choose between these two phones, I would pick the OnePlus 8T. While the Samsung Galaxy M55 offers a larger battery and newer software, the significantly better performance of the Snapdragon 865, much brighter display, and faster charging make it a more compelling option for my personal use. I value smooth performance and a good display more than the marginal benefits of a larger battery and newer software. Additionally, the stereo speakers would provide a more enjoyable media consumption experience.
