I just bought a Razer Blackwidow and a Steelseries 6Gv2 for a really good deal of only $70.
I mainly wanted to buy a blue switch board, the Steelseries is just extra.
But after comparing both boards for a while, I actually prefer the Cherry MX blacks for typing!! Kinda odd, but I like it because when you don't bottom out the keys, not only it doesn't take much force to press, the stiff sping actually provides a damping effect that gives a gentle feel to the switch. Blue and brown switches, on the other hand, is a bit more difficult not to bottom out, which gives you a harsh landing feedback, sending a shock back to your fingers. Not comfortable.
The feel of the Blue switch is immediately addictive, while the brown addiction is chronic but very hard to get off.
Yet the feel of the black switch has a miraculous healing effect, like the smile your guardian angel.
