My Choice: OnePlus 8
Even though the OnePlus 8 is an older phone, its significantly superior performance, stunning AMOLED display, faster charging, and overall more premium experience make it the clear winner for me. The Nokia G21's larger battery is a tempting advantage, but the performance difference is too substantial to ignore. I value a smooth and responsive user experience, and the OnePlus 8 delivers that in spades. The significantly better display is also a major factor, as I consume a lot of media on my phone. While the Nokia G21 might be a suitable option for budget-conscious users with basic needs, the OnePlus 8 offers a far superior overall package for a slightly higher investment. The lack of specific details about the Nokia G21's display brightness and build materials further solidifies my choice of the OnePlus 8.
