My Choice

If I were choosing between these two phones, I'd go with the Samsung Galaxy S21 FE 5G. Even though the Realme 9 Pro offers some great features, especially in battery life and price, the S21 FE's overall package is just too compelling. The significantly more powerful processor is a must for my daily needs as a tech journalist.

The additional sensor and better build are very important to me as well, since I want to get a phone that lasts for as long as possible.

While the Realme 9 Pro is a solid device, the Samsung Galaxy S21 FE 5G offers a far superior user experience that aligns much closer with my priorities. It’s a device that truly excels in most aspects, and I believe that it is a more sensible choice for anyone who wants to enjoy a great phone for the coming few years.
