My Choice and Explanation

Based on a combination of personal preference and the analysis provided, I would choose the Samsung Galaxy S21+ 5G.

Here's why:

  1. Display Brightness: I often work outdoors and need a display that is easily visible in bright sunlight. The S21+'s significantly higher brightness is a crucial advantage for me.
  2. Camera Versatility: I value having a high-quality camera system with multiple lens options, including optical zoom. The telephoto lens and 8K video recording capabilities of the S21+ are compelling.
  3. Performance: While I'm not a hardcore gamer, I do appreciate smooth performance and the ability to handle demanding apps without any lag. The S21+ offers a noticeable performance edge.

While the Xiaomi offers faster charging and a bigger battery, these are not as important to me as display brightness, camera versatility and performance. The S21+ fits my use case best, even if it comes at a slightly higher cost. It is also important to note that, while the Xiaomi has better video scores on DxoMark, the S21+ supports higher video resolutions, which would be necessary for high quality content creation.
