My Choice
If I had to choose between these two phones, I would choose the Realme 8. Although the 90Hz screen and better selfie camera of the V21 5G are appealing, the superior performance, significantly larger battery, and higher display brightness of the Realme 8 are more aligned with my priorities for an all-around device. I appreciate a phone that has a screen that is easy to view in bright light, that has great battery life, and is more powerful. While the 90Hz screen is a nice touch on the V21 5G, I think the 60Hz is sufficient, while the performance and brightness benefits are greater on the Realme 8.
