What I would choose and why!
I would choose the ZTE nubia Z50S Pro.
While the vivo V21 5G offers a more compact and lightweight design, the ZTE nubia Z50S Pro simply excels in almost every other meaningful category for a modern smartphone user. The drastically more powerful processor, superior display, vastly improved camera system, significantly larger battery with faster charging, and more future-proof connectivity make it a far better overall device. The V21 5G's advantages are limited to its slightly lighter weight, higher-resolution selfie camera, and macro lens which do not outweigh the benefits of the Z50S Pro. The performance difference alone is night and day and will be noticeable in all aspects of the user experience, from simple browsing to demanding gaming, making it a far better long-term investment. I also enjoy media consumption and appreciate the larger, brighter, smoother screen, and the significant camera upgrades, along with the better sound from the stereo speakers, are important for me.
