As mentioned pretty much up to personal preference. As a rough gauge in cases for cherry mx, red is pretty smooth, less actuation force. Blue is clicky (and loud but satisfying), when depressed will feel a click. Brown is in the middle of both, feel abit of the actuation click (not loud like the blue ones) but generally still smooth. Black switch not sure but iirc it has more actuation force. For the keyboard experts there correct me if I'm wrong. There are people that says reds are good for typing, blues for gaming and Browns for abit of both. It's all up to personal preference, I own a Corsair K70 RGB Cherry Brown. Pretty satisfied with it. Hope it helps
