Keyboards are keyboards.
Corsair makes good products but their software is a nightmare.
On my most recent build, I took all corsair products (Hub, AIO, Fans, Mouse, Keyboard, Companion display) and its been mediocre mostly due to iCue, but their support is pretty good.
Key thing to buying a keyboard is you should take a visit to a bestbuy or microcenter, and first find out what type of switches you like. That is probably the best driver for how much you will like your keyboard. Other than that sometimes there are unique features you might enjoy but that is less likely.
I had a bad experience with Steelseries, so I won't buy their products anymore.
I REALLY like EVGA as a company, so I might try their peripherals in the future, or Logitech.
