My Choice

If I were choosing between these two, I'd personally go for the Samsung Galaxy S21 FE 5G. Here's why:

While the Z Flip4 has a cool form factor and a powerful chip, the S21 FE 5G hits my sweet spot for a well-rounded experience. As a tech journalist and smartphone analyst, I often use my phone for research, writing, capturing photos, and consuming content. The S21 FE 5G’s superior battery life is a significant advantage, as I don’t like to worry about finding a charger during a busy day. The AMOLED screen is fantastic for everything from reading articles to watching videos, and it is very visible outdoors, which is ideal for me as I work while on the go sometimes.

Moreover, I do enjoy photography, and the S21 FE 5G's camera setup is more flexible and reliable with its telephoto and better selfie capabilities. While I appreciate innovation, for my everyday needs, a reliable, solid phone with a focus on battery, display, and camera performance is more beneficial. And, the extra year or so of software updates helps with device longevity.

Ultimately, both are great phones, but for me, the S21 FE 5G's balance of features, battery, and a slightly better price point makes it the more practical choice.
