Best Gaming Keyboard?

Trying to find the best gaming keyboard to buy.

I'm being told Corsair K70 RGB . The blackwidow chroma looks good but I'm told they are cheap cherry knock offs.
Also being told CM storm is a good option.

I was told to stay away from Razer and logitech.

I need your help. Cost isn't an issue. But of course cheaper is better- I just want a very very goodgaming keyboard that will also last a long time.

SO; this is what I'm thinking about getting as of right now...

OR

In regards to the corsair, the switches I am told are like this:
Red - Gaming
Blue - Typing, bad for gaming
Brown - Happy medium

Also told corsair is good hardware but shit software, and that can be googled.
razer chroma gloats about their switches on the chroma packaging... but the are they better that the corsair red?
I don't want them too loud or stiff either, in case for media recordings, as well ascarpal tunnel
