  2. How important is camera versatility to you? If you need optical zoom and a wide range of camera features, the S21 FE 5G wins, the X3 GT only has basic features.
  3. Do you value size and weight? If a thinner, lighter phone is important, the S21 FE 5G is preferable.

Final Recommendation

If I had to choose, I'd personally lean towards the Samsung Galaxy S21 FE 5G. While the Poco X3 GT has its advantages, the S21 FE 5G offers a more balanced and premium experience. Its superior display, more versatile camera, and wireless charging add significant quality-of-life improvements. As someone who values great display quality and camera for everyday photography, the S21 FE 5G better fits my requirements, even though it has a slightly slower charging speed and less battery capacity. The performance difference is also there, and overall is a better pick.

It all boils down to what you value most in a phone. Both phones are great options, but the S21 FE's edge in display, camera, and overall polish makes it the more compelling choice for my use case.
