What I Would Choose and Why

If I were choosing between these two devices, I would personally select the Samsung Galaxy S21 Ultra 5G. Here’s my reasoning:

  1. Overall Versatility: The S21 Ultra offers a much more well-rounded experience that fits my personal needs and requirements. I value having a device that excels in multiple areas such as photography, performance, and display quality.

  2. Superior Camera Capabilities: As someone who enjoys photography and videography, the S21 Ultra's advanced camera system is extremely attractive. The higher resolution sensors, telephoto lenses, and 8K video capabilities make it a superior choice for capturing high-quality content.

  3. Display Quality: The AMOLED display on the S21 Ultra is much better than the Tab S9 FE+'s IPS LCD. The vibrant colors, deep blacks, and higher brightness make for a better viewing experience.

  4. Portability: The compact design of the S21 Ultra makes it more convenient to carry around and use daily. The Tab S9 FE+ is quite large, and not ideal to carry.

  5. Performance: The S21 Ultra's higher AnTuTu score indicates that it has better overall performance in the majority of tasks I would be doing on my device.

While the Samsung Galaxy Tab S9 FE+ has its strengths—particularly in battery life and screen size—it doesn't align with my priorities as well as the S21 Ultra. If my focus were solely on media consumption or having a tablet-like experience with long battery life, the Tab S9 FE+ would be a better option. But, for my use case, the S21 Ultra is the superior choice, offering a more complete mobile experience.
