  • Mobile Gamer: S23 FE is the winner with higher performance.

My Choice

If I were choosing between these two devices, I would pick the Samsung Galaxy S23 FE. Despite the S21 FE being a lighter and more comfortable phone, for me, the improvements in performance and camera quality in the S23 FE are too significant to ignore. I would also like to have an extra year of Android support. As a tech journalist and someone who often pushes devices to their limits with mobile gaming and photography, the S23 FE would be the most practical tool for me. While the brighter screen on the S21 FE is compelling, it is not enough to compensate for the S23 FE's advantages.
