The Verdict

Apple's MacBook Air 15 M3 and Samsung's Galaxy Book4 15 serve different user needs at substantially different price points. The MacBook Air commands a $550 premium with its superior 2880x1864 Liquid Retina display (500 nits brightness versus 300 nits), exceptional 18-hour battery life from a 66.5 Wh cell, and the efficient M3 chip that handles everyday tasks and creative work with minimal fan noise. Its aluminum unibody at 1.51 kg feels lighter and more premium. However, the Galaxy Book4 offers surprising value with double the storage (512GB versus 256GB), 16GB RAM versus 8GB, and a more versatile port selection including HDMI and USB-A. The Intel Core i7-1355U provides adequate performance for productivity, though it generates more heat than the M3. Battery life lags noticeably at 10 hours. Windows 11 provides broader software compatibility, while macOS excels in cohesion and user experience. Choose the MacBook Air if you prioritize display quality, battery endurance, and ecosystem integration. Pick the Galaxy Book4 if budget matters most, you need Windows software, or require maximum expandability and traditional ports. The MacBook Air's advantages justify its price for creative professionals; the Galaxy Book4 represents better value for budget-conscious productivity users.
