As a tech journalist and someone who appreciates quality in both build and performance, the S21 FE simply offers a more well-rounded and premium experience. While the Moto G51 has its merits in being affordable and having a large display, the S21 FE's superior display, faster performance, advanced camera features, faster charging, and build quality make it a better long-term investment.

The real-world benefits of the S21 FE, especially the brighter AMOLED display for outdoor visibility, the significant performance boost for smoother operation, and the much better camera quality for both photos and videos are difficult to ignore. While the larger battery of the G51 is tempting, the speed of charging and the additional features of the S21 FE make it an easier pick for me.

Ultimately, the S21 FE gives me the features and performance I value most, even if it means a slightly higher price point. It's a better fit for a demanding user who wants a premium smartphone experience.
