Our Verdict
Corsair K70 RGB TKL
Ducky One 3
The Corsair K70 RGB TKL and the Ducky One 3 are outstanding mechanical gaming keyboards. The Corsair is a TenKeyLess keyboard available with linear Cherry MX Speed switches or linear Cherry MX Red switches. It has dedicated media keys and a volume wheel. It also has dedicated software for changing settings or setting macros, while the Ducky only allows you to adjust settings directly on the keyboard itself via button combinations. On the other hand, the Ducky comes in a variety of MX Cherry switches. It's also a hot-swappable keyboard, so you can install the switches you prefer. Both keyboards have exceptional latency, and you won't notice any delays gaming on either.
