My Choice

If I were choosing between these two phones, I would pick the Samsung Galaxy S21 5G. While the Moto G Stylus 5G has its appeal with its larger screen and stylus, the Samsung S21 excels in almost every other category that is important to me. The vastly superior performance of the Exynos 2100 chipset, coupled with the amazing AMOLED display with a 120Hz refresh rate, would make a huge difference in daily use. Additionally, the camera system of the S21 is a big draw. I prioritize a smooth, responsive, visually appealing, and high-performance phone. While the lack of expandable storage is a minor drawback, the overall package of the S21 far outweighs its limitations. For me, the enhanced user experience, especially in terms of display, speed, and camera, is worth the extra investment, and I'd like to have a device that will last me for several years and retain value.
