My Choice
If I were choosing between these two phones, I would pick the Samsung Galaxy S21 5G. While the Realme C53 offers a larger screen and longer battery life, the S21's superior display, vastly superior performance, significantly better camera system, and premium features outweigh the C53's advantages for me. I value the quality of the display, the versatility of the camera, and the overall performance that the S21 provides, which makes it the better overall smartphone, even if it is older. The S21 also has much better brightness, meaning it's actually usable in outdoor settings. I find this to be an essential feature for most users. The S21 battery life is adequate for a day's use and the faster charging of the C53 isn't enough to offset the other advantages of the S21. For me, the C53 is too compromised in the areas that matter most.
