  • Scenario 4: You prefer a more pocketable phone: Choose the vivo V21 5G, because it's smaller and lighter than the Mi 11.

My Choice

I would choose the Xiaomi Mi 11.

While the vivo V21 5G has its strengths, particularly its lighter design and superior selfie camera, my priority is performance, display quality, and a more versatile camera system. The Xiaomi Mi 11 offers a significantly better overall experience for my needs, which include mobile gaming, media consumption, and photography. The higher-resolution display, faster chipset, wireless charging capabilities, and larger battery are significant advantages that justify choosing the Mi 11 over the V21 5G. While the Mi 11 is larger and heavier, these are trade-offs I am willing to accept for the improved performance and media experience. Additionally, having a brighter screen would be a big plus for me as I often use my phone outdoors in direct sunlight.
