My Choice
I would choose the Xiaomi Poco F4 GT. While the vivo V21 5G is lighter and has a better front-facing camera, the Poco F4 GT's dramatically superior performance, larger battery, much faster charging, better audio, and newer software make it a more versatile and future-proof choice. For general everyday use, its improved processor and display refresh rate would provide a snappier, smoother experience and for the times I would need to run demanding applications or play high-end games, the Poco F4 GT would offer much better overall performance. Additionally, the superior screen protection and advanced location tracking are nice benefits that are missing on the Vivo V21 5G. Even though the front-facing camera isn't as high resolution, the larger sensor makes up for it in image quality and low light performance. I am willing to sacrifice the front facing camera and slightly smaller form factor of the Vivo for the vastly superior processing power and overall user experience offered by the Poco F4 GT.
