What I would choose and why
I would choose the Samsung Galaxy A33 5G. Here's why:
While the vivo V21 5G boasts a superior selfie camera and a lighter design, the overall package of the Samsung Galaxy A33 5G aligns better with my needs and preferences. The significant improvement in performance with the Exynos 1280 chipset, combined with the much larger 5000mAh battery, provides a more reliable and powerful daily driver. Additionally, I value the superior audio quality from the A33's stereo speakers and Dolby Atmos, as well as the extended software support which provides added longevity. Although the V21 offers a lighter build, the slight increase in weight and thickness of the A33 is an acceptable trade-off considering its other advantages. The presence of Gorilla Glass 5 on the A33 also gives peace of mind for its daily protection. In summary, the A33 offers a more well-rounded experience for my daily use and would be my preferred choice between the two devices.
