My Choice
I would choose the Realme GT 5G. The significant performance advantage offered by the Snapdragon 888 chipset, coupled with the smoother 120Hz display and faster charging, is a much bigger gain compared to the marginal advantages of the Samsung A15 5G for my needs. I prefer the more feature rich camera and audio capabilities. The battery will still last for a full day with moderate use, and I value the performance of the phone. While the Samsung has more recent Android, this is not as important to me as the significantly better performance and camera features of the Realme. The trade off of battery life and a newer os for significantly more power is acceptable.
