My Choice
Given the specifications and my understanding of user needs, I would choose the Oppo Reno6 5G.
Reasoning:
The Oppo Reno6 5G offers a more well-rounded experience due to a significantly more powerful processor, a brighter screen which is usable in sunlight, a longer lasting battery with fast charging, versatile photography with a telephoto lens and better image quality from the main camera sensor, and superior connectivity with Wi-Fi 6 and Bluetooth 5.2. While the vivo V21 5G has advantages in selfie camera and video stabilization capabilities, the Oppo's comprehensive performance and overall user experience are more compelling for a broader range of users. I would also be willing to sacrifice the slightly better selfie camera and OIS in all video resolutions in favor of significantly better performance, battery life and better outdoor visibility and general camera performance from the main camera. As someone who uses my phone frequently and takes photos across multiple scenarios, the Oppo is a more logical choice for me.
