My Choice

I would choose the Xiaomi Redmi Note 13 4G.

Here's why:

While the Vivo V21 5G has an impressive selfie camera and 4k video capabilities, the Redmi Note 13 4G offers a more well-rounded experience for my daily usage. The larger, brighter 120Hz display is ideal for media consumption, and the significantly larger battery means I don't have to worry about running out of power. Additionally, the stereo speakers with Dolby Atmos would enhance my media-watching experience. The slightly better performance for gaming (compared to the V21) and more storage options, as well as a newer Android version, solidify this choice for me. For my use case, having a phone that can reliably last through a full day of work and media consumption takes priority over superior selfie capabilities.
