Our Verdict

Logitech K840

HyperX Alloy FPS Pro

The HyperX Alloy FPS Pro is much better than the Logitech K840. The HyperX has a significantly better build quality and backlighting, while the Logitech doesn't have backlighting and has cheap pad printed keycaps. The HyperX's Cherry MX Red switches provide a much better typing experience compared to Logitech's Romer-G switches, but the Logitech has software support and programmable keys.
