My Choice
If I were to choose, I would select the Samsung Galaxy S21 5G. While the Xiaomi Poco F4 GT boasts superior performance, its larger size, heavier build, and lack of camera system specifications makes it a less versatile device. I value a compact form factor, a bright, quality display for outdoor use, and a well-rounded camera system for diverse photography and videography, which the Samsung offers. The S21 5G's wireless charging capabilities are an added convenience for me. Though the F4 GT has a larger battery, I prioritize overall daily usability over raw performance and fast charging. The Samsung also has a better software upgrade path as well as better overall reviews for its cameras. While I appreciate that the F4 GT has a larger screen, the size of the phone doesn't lend itself to portability and ease of use that I prefer. Therefore, the Samsung is the more suitable device for my specific requirements.
