My Choice and Explanation
I would choose the Samsung Galaxy S21 5G. While the Honor X7a offers a larger battery and newer OS out of the box, the S21 surpasses it in almost every other critical aspect. The difference in display quality (AMOLED vs TFT LCD, 120Hz refresh, higher brightness), raw processing power (Exynos 2100 vs Helio G37), and the camera system is massive. As someone who uses my phone for many tasks from gaming to media to photography, the S21 offers a far superior experience. The additional features like wireless charging, better Wi-Fi, and a more durable build also make it a more compelling option. The S21 also has a higher maximum version available, and can keep up with modern OS updates. While battery life is slightly lower on the S21, the higher performance and feature set outweigh this single trade off, for me.
