My Choice
I would choose the Xiaomi Poco X5 Pro. While the vivo V21 5G's design and selfie camera are compelling, the Poco X5 Pro's advantages in performance, battery life, display quality, connectivity, and audio features align better with my typical use case. I value smooth performance, a longer-lasting battery, and a more immersive multimedia experience over selfie camera quality. The significantly higher benchmark scores, superior display, larger battery, and faster charging on the Poco make it the more future-proof and versatile device. While I do like the OIS on the V21 5G and would miss it, the Poco X5 Pro provides a better overall experience, and the side fingerprint sensor is more practical.
