What I Would Choose and Why!

If I were buying a phone for myself, I would choose the Samsung Galaxy S21 FE 5G.

The slightly shorter battery life is a trade-off I'm willing to make for the increased power and premium experience. For my lifestyle and technological preferences, it's the better all-around device that is more capable in several scenarios and will likely provide a more fulfilling mobile experience.
