My Choice
Given the choice, I would choose the vivo V21 5G.
While the Realme C53 has a compelling advantage in battery life and a newer Android version, the superior display (AMOLED vs. IPS LCD) and significantly better performance of the Dimensity 800U chipset in the V21 are more important to my needs and preference for a fast and fluid phone. The camera system on the V21 is far more versatile and is better quality. I also value the better video recording capabilities. Although the battery on the V21 is smaller, it's still sufficient for a full day of moderate usage, and I am willing to trade off some battery life for a superior overall experience.
