My Choice
If I were choosing between these two phones, I would pick the Motorola Razr 50. Here's why:
While the vivo V21 5G has a better selfie camera on paper, the practical advantages of the Razr 50 are more compelling. The newer chipset provides substantially better performance, which is a key factor for my daily usage. The higher refresh rate and dramatically brighter screen make for a much more pleasant user experience, especially in bright conditions. I value the convenience of wireless charging and the added versatility of a foldable design and the e-SIM capability.
The trade-offs, such as the marginally lower main camera resolution and the absence of a dedicated macro lens are less important to me than the performance and more modern feature set offered by the Motorola Razr 50. Despite the Razr 50 being a more expensive choice, the overall user experience with its advanced features and processing power would make the investment worthwhile for my use case.
