My Choice and Why

If I were choosing between these two phones, I would pick the Samsung Galaxy S21 Ultra 5G. While it's an older device, it offers a superior experience in nearly every aspect that matters to me. The significantly better display with its AMOLED technology and higher resolution is a major draw, especially for someone who watches videos and reads articles frequently. Additionally, I value the versatility of its multi-lens camera system, including the telephoto lens, and its video capabilities. The better performance, thanks to its more powerful chipset and GPU, also means that the phone will be smoother and more responsive in daily use and will handle more demanding applications with ease. Although it lacks the weight advantage and faster charging of the Realme C67, the premium features of the S21 Ultra justify its higher price point and slightly less convenient design aspects for me. The overall quality and features that come with the Samsung Galaxy S21 Ultra make it the clear winner for my personal needs and usage.
