Our Verdict

Razer BlackWidow

Corsair K70 RAPIDFIRE

The Corsair K70 RAPIDFIRE is better overall than the Razer BlackWidow for most uses. The Corsair has a wrist, dedicated media keys, a USB passthrough, and it has a better typing quality. However, the Razer has onboard memory, and it has full RGB backlighting.
