My Choice

I would choose the Samsung Galaxy S21+ 5G. While the Galaxy A13 has a newer Bluetooth version, a slightly larger battery and a more practical fingerprint sensor placement, it cannot compete with the performance, screen quality and camera capabilities of the S21+. The significantly faster processor, superior display technology and the far more advanced camera with OIS and optical zoom are compelling reasons to choose the S21+ if the budget allows it. I also value having a more fluid and responsive user experience as well as having access to a better camera and I am willing to pay more to achieve that. I also find the wireless charging feature very convenient for daily usage, something that the A13 doesn't offer. While the price difference is significant, the user experience and quality of the S21+ is clearly superior in all the important aspects.
