My Choice
If I were choosing between these two, I'd lean towards the Motorola Moto G31. The AMOLED display is a game-changer for me. The visual quality difference is immediately noticeable, and I personally value vibrant colours and deep blacks over everything else. While the slower charging and older OS would be a slight inconvenience, the better overall multimedia experience with Dolby Atmos audio and the better camera make it the winner for me. Plus, I tend to be diligent about charging my devices, and so the 10W is not a huge factor.
