My Choice
If I had to choose between these two phones, I would pick the Google Pixel 8a. While the vivo V21 5G has a larger screen and faster charging, the Pixel 8a offers a significantly better overall experience. The Tensor G3 chipset provides a noticeable leap in performance, making it smoother and more responsive for daily tasks and demanding apps. The camera system is far more advanced, offering better image quality and more features. Also, the Pixel 8a gets you up to date software and security.
For me, the slightly smaller screen and slower charging are acceptable trade-offs for the vastly superior performance, camera, and future-proof nature of the Pixel 8a.
