The Verdict

These laptops serve fundamentally different audiences and price points. The Lenovo IdeaPad Flex 5 delivers solid everyday performance with its AMD Ryzen 5 7530U, 8-16GB RAM options, and 14-inch 1920x1200 IPS display at $649, making it excellent for students and budget-conscious professionals handling office work and light multitasking. Battery life reaches 12 hours, and the 1.55kg weight suits portability needs. However, storage maxes out at 512GB and the 60Hz refresh rate feels dated. The Samsung Galaxy Book4 Ultra ($2,399.99) operates in a completely different tier with its Intel Core Ultra 9 185H, 16GB LPDDR5X RAM, and 1TB expandable storage providing workstation-class performance for content creators and power users. Its 16-inch Dynamic AMOLED 2X display with 2880x1800 resolution, 120Hz refresh, and 400 nits brightness vastly outperforms the Lenovo for creative work. Thunderbolt 2 ports and 13-hour battery life add professional flexibility, though its 1.86kg weight is noticeably heavier. Choose the Flex 5 if budget matters and you need a reliable productivity machine; pick the Galaxy Book4 Ultra if you demand premium performance, display quality, and expandability for professional applications. These aren't competitors but rather products for different financial and performance requirements.
