My Choice
If I were choosing between these two phones, I would pick the Xiaomi 12. The reason is its overwhelming advantage in processing power, display quality (120Hz and brightness), significantly faster charging and the inclusion of wireless charging, and the better camera (more versatile video features). While the vivo V21 5G has a better front camera, it's overall feature set and performance falls far short of the Xiaomi 12, making the Xiaomi 12 the better all-round smartphone with modern features. The difference in performance, screen brightness, and battery charging speed is so significant, that I would opt for Xiaomi 12.
