Pick the Swift 14 AI if your top frustration with your current device is running out of charge before the day ends — endurance is the lead spec here. The biggest gaps in its favor are claimed battery life, weight.
Pick the Galaxy Book4 Ultra if the display is what you stare at all day — refresh rate, brightness, or sharpness is where the difference will be most visible. Its strongest claims are ram, cpu cores, screen size, among others.
