My Choice
If I had to choose between these two phones, I would personally pick the vivo V21 5G. While the Redmi 10 does have a larger battery and a side-mounted fingerprint sensor, I prioritize screen quality, performance and camera quality, and the V21 5G simply offers a better experience in these areas. The AMOLED display will be much better for day to day media consumption, and the 4K video recording with OIS is a huge plus that the Redmi 10 simply cannot match. The Dimensity 800U is also a much more powerful chip, and will offer a snappier experience than the Helio G88. While battery life is a very important factor, the V21 5G still has decent battery life for all-day use, and the significantly faster charging will mitigate any disadvantage in that department.
