Personal Choice and Rationale
I would choose the vivo V21 5G.
While the longer battery life of the Redmi Note 10 5G is appealing, the superior AMOLED display, significantly better front and back cameras (including the ultra-wide lens), and much faster charging of the vivo V21 5G make it the better choice for my needs. The video recording capabilities of the V21 5G with OIS and Ultra-Stable Video is also something that I would value for content creation, and it's difficult to overlook the massive upgrade on the front facing selfie camera. Although the battery life is smaller, the faster charging will be able to offset this in most use cases. I also value the thinner and lighter design of the V21 5G, which would make the phone more comfortable to carry around for longer periods. For me, the better camera, display, and video quality outweigh the larger battery and slightly higher performance of the Redmi Note 10 5G.
