The keys are quieter than mechanical switches (they make more of a soft ‘thunk’ than a ‘clack’). Typing speed and accuracy are quite good. I only use it for work, though, so I have no idea how well or poorly it would perform for gaming or other tasks.
Sadly it's apparently impossible to buy those switches by themselves (for a custom build) without desoldering from a donor board.
I had an office neighbor who used one of these things. Obnoxious and loud. Personally, I fought back by playing the teletype sound effect that would play in the background on 1010 WINS in NYC at moderate volume to improve my cognitive function.
The Falcon Z-77 87 Key Mechanical Keyboard is my most recent acquisition. Being left handed I don't need the num pad as it is on the wrong side, however, due to moving away from Vim I did want those home/end keys, hence the 87 key keyboard with novelty programmable backlit keys. I can grey out the useless Windows keys and get the important Vim keys in green!
This I do get tired of though, so, if writing words rather than code I swap over to my Logitech K810 where there are no home/end keys. This is a soft touch keyboard with backlighting and no 'noise pollution'.
Then there are the built in laptop keyboards to use too.
IMHO the Chromebook keyboard layout is the future.
Variety in keyboards is an accidental discovery, with the Logitech K810 it works across devices - up to three - and with Synergy it works across more. I had thought that getting the optimal keyboard was the way to go, whereas in use I prefer the occasional change.
The keyboard that does get the most questions is none of the above, it is the 'Tron' style flat keyboard on my Lenovo Yogabook that doubles up as a drawing tablet.

Cargo cult (which could also be on the inverse side).
Nobody measures anything in this industry -- like the relative RSI or typing speed between the two kinds of keyboards. So people can go around and stick to their personal preferences (even while they could slow them down compared to the other type of keyboard), and insist of their superiority, what actually holds true be damned.
