Should I choose Samsung Galaxy S5 or Samsung Galaxy S6?

Verdict: Choose the Samsung Galaxy S6 first for its substantially superior Quad HD display, 14nm 64-bit performance, OIS-assisted f/1.9 camera, and modern charging conveniences, unless hardware modularity, IP67 water resistance, or microSD expansion on the Samsung Galaxy S5 are strictly mandatory.

The Samsung Galaxy S6 is the superior choice for most users due to its major leaps in display sharpness, processing architecture, and camera stabilization, while the Samsung Galaxy S5 remains preferable solely for users who demand a removable battery, microSD expansion, and IP67 water resistance.

The Samsung Galaxy S6 represents a major generational upgrade, delivering a sharper 5.1-inch Quad HD display (2560x1440, 577 ppi) compared to the Samsung Galaxy S5's Full HD screen (1920x1080, 432 ppi). Internally, the Galaxy S6 replaces the Galaxy S5's 28nm 32-bit SoC, 2 GB LPDDR3 RAM, and eMMC storage with a significantly faster 14nm 64-bit Exynos 7420 octa-core processor, 3 GB LPDDR4 RAM, and high-speed UFS 2.0 storage. Photography is also markedly improved on the Galaxy S6 thanks to an f/1.9 aperture and Optical Image Stabilization (OIS), outperforming the Galaxy S5's unstabilized f/2.2 camera. However, this shift comes at the cost of hardware utility: the Galaxy S5 retains a larger, user-removable 2,800 mAh battery, a microSD expansion slot supporting up to 128 GB, and IP67 water resistance, whereas the Galaxy S6 opts for a sealed 2,550 mAh battery with fast and wireless charging in a slimmer 6.8 mm, 138 g glass-and-aluminum unibody.
