To my ears, they are equally loud, but the blue Cherries have a more ... penetrating? ... sound. Makes them fun to type on, but potentially more annoying to anyone listening.
The Customizer just sounds like you're doing hard graft. When did that become unacceptable in an office? Seems to me we are expected to put up with the constant harassment of phones ringing, and people yakking away in the background, yet the sound of someone using the right tool for the job is considered intrusive. Sorry for the rant.:yell:
