My Choice
If I had to pick between these two phones, I would choose the Xiaomi Poco X6. While the Samsung S21 has the better performance and camera system, the Poco X6 offers a much more appealing overall package for my usage. The larger, brighter display combined with significantly better battery life and faster charging are critical for my everyday usage. Although the S21 has a slight edge in pure processing power and camera versatility, the Poco X6's more modern design, efficient chipset, and increased storage/RAM make it a very solid pick. I also don't use a smartphone for photography as a priority, which makes the less versatile camera system of the Poco X6 less of an issue for me.
The Poco X6 simply addresses my key needs and priorities more effectively, and at its reasonable price point it's the better buy in my opinion. I need an all rounder that focuses on a good media experience, with the ability to also perform well in daily tasks.
