While the Samsung Galaxy S23 is a well-rounded phone, the ROG Phone 8's significant advantages in performance, battery life, display, and expected gaming features make it the more compelling choice for me. I value a smooth and responsive user experience, long battery life, and a large, immersive display for media consumption. The extra weight and size are acceptable trade-offs for these benefits. The newer, more powerful hardware ensures the phone will remain capable for longer. While camera quality is important, I prioritize the overall user experience and longevity offered by the ROG Phone 8. The lack of specific details on the ROG Phone 8's telephoto camera is a minor concern, but the overall package is still more appealing.
