The Samsung Galaxy S23 Ultra boasts a significantly brighter display (1274 nits peak) with an infinite contrast ratio, offering a more vibrant and immersive viewing experience. The ROG Phone 5s has a good display, but lacks the sheer brightness and contrast of the S23 Ultra. Both have high refresh rates (144Hz on ROG, 120Hz on S23 Ultra) for smooth visuals.

Camera Comparison

The Samsung Galaxy S23 Ultra's camera system is a clear winner. It offers incredible versatility with multiple lenses, exceptional image quality in various lighting conditions, and impressive video recording capabilities. The ROG Phone 5s has a decent camera, but it doesn't compete with the S23 Ultra's flagship-level performance.

Performance

While the ROG Phone 5s' Snapdragon 888+ is a capable chip, the Samsung Galaxy S23 Ultra's Snapdragon 8 Gen 2 offers a noticeable performance advantage. The S23 Ultra's CPU and GPU are newer and more efficient, resulting in smoother multitasking and better sustained performance, especially in demanding games. The ROG Phone 5s' cooling system helps mitigate throttling, but the S23 Ultra generally maintains higher clock speeds.

Battery Life
