well, basically,
people complaining about the noise produced by the keyboard after u press it.
as i can say, it not loud like hell, people always said that they might wake up their friends while playing.
and my thought is    . if you are not SDO fan, well dont bother about the noise from the keyboard.
as i saw 1 of my friend, playing SDO using the conventional membrane keyboard, hell the noise is very annoying.

another thing is about the clicky tactile.
but if you havent using any other switches, i bet you wont have any problem with it as you will get used to it.
its not like MX Black switch, which you need a lot of force to press it, around 80g(peak) while the MX Blue is only 60g(peak).

in my thoughts, the major fail with BW keyboard is the keycaps design,
well, not all keycaps got problem. you just need to pay attention on SPACE, ALT, SHIFT adn CTRL keys.
as it will stick on each other when u press it. but it base on luck. some people got non of this problem at all.

my opinion for yous is, stop hearing review, just step to the nearby shops(if got) and test it your self.
everybbody got their own preference, choosing a keyborad is like choosing a headphone.
Normally people would say like this,
MX Black = good for gaming
MX Red = Good for both gaming and typing.
MX Brown = Same like Red, got at both.
MX Blue = Worst for everything.   

To sum it up, i dont have any complains with my blackwidow, sticky keys only with my Space and ALT buttons.
