My Choice
If I were choosing between these two phones, I would pick the vivo V21 5G. The primary reason is the significant difference in performance. The Dimensity 800U chipset is notably more powerful than the Helio G80. As a user who values smooth and responsive operation for multitasking and gaming, this is a critical advantage. Additionally, the AMOLED display on the V21 5G is far superior to the LCD on the A13, providing a much better viewing experience.
While the Galaxy A13 does offer a larger battery and Gorilla Glass 5 screen protection, these advantages are not as important to my typical use case as the superior performance, display, and camera. I prefer fast charging in my day-to-day, and the 33W fast charging on the V21 would mitigate the battery difference to some degree. The better cameras on the V21 would be a plus as well for everyday use.
Ultimately, the vivo V21 5G offers a superior user experience, making it the better choice.
