  5. Audio Quality: Stereo speakers with Dolby Atmos support improve the overall media experience for music and video.

While I acknowledge that the vivo V21 5G has its advantages, such as a lighter design and better front camera, these are secondary to the performance, display and camera versatility that the Oppo Find X3 Pro offers.
