My Choice

If I were choosing between these two phones, I would pick the Samsung Galaxy S21 5G.

Reasoning:

My primary use case involves heavy media consumption, including streaming videos, playing games, and browsing the web. The S21's vastly superior display, with its larger size, higher resolution, AMOLED technology, 120Hz refresh rate, and higher brightness, would greatly enhance my viewing experience.
