The loudest of the lot is the Blue. This type of switch is ideally suited for typing thanks to the construction of the slider. The two-piece design results in a larger hysteresis and a clicky sound when the tactile point is crossed. The actuation force is usually 60g across all brands. In a nutshell, this switch is great for typing and not for activities like spamming. The popularity amongst gamers also stems from the satisfaction that comes with the click sound associated with it.
