Our Verdict

Logitech K840

HyperX Alloy Core RGB

The Logitech K840 is significantly better than the HyperX Alloy Core RGB. The Logitech has a better build quality thanks to its aluminum plate, and it has mechanical switches that feel light and responsive. The Logitech has software support for customization, but it doesn't have dedicated media keys like the HyperX, and typing noise can be louder if you bottom out the keys.
