I'm wondering what is the actual "best" mechanical gaming keyboard in terms of performance, currently available? Searching in Google and asking around in other forums turn up that Filco boards, despite apparently being designed for office use, is actually the best option for enthusiasts.

Is this really true, even beating companies dedicated to gaming peripherals such as Razer's Blackwidow and Steelseries' Z-Board? If so, I'm going to look for one just to test it out.
